You know, I still love the looks of that machine. What an artist the guy was who built it. Was not at Amana last Fall and I forgot about it. Thanks for posting the link Dennis.

Emery --- in 2010 you posted...


It was built by one of our gmcMI members, Bob Lehman of Dubuque, IA.
He used a new 35 foot Spartan motorome chassis with a rear diesel pusher.

He used three gmc Motorhomes to make it. The top of he gmc is about 23" higher than a normal gmc.
He used his original gmc as the front top piece. He cut off the body at the beltline and raised it up and built an aluminum frame between the chassis and the bottom of the gmc body.
He has made the lower section with several doors and the panels looks about like the original gmc. The proportions are great and the overall look is like a supersize gmc. The only thing that might have looked good would be to have another axle in the rear so that it looked exactly like a bigger gmc. Right now it have only the dual rear single drive axle.

He had it for sale at the Amana Convention but I don't know if it has been sold.

I think Kerry hit the nail exactly on the head!  I feel I can prove it too! 
 
I used an existing Workhorse chassis (LF-72), plopped a GMC body on top of it.  What happened was-- the rolling chassis with all the fancy new electronics (OBD--ABS, Duramax Turbo diesel, Allison 5 speed, front wheel drive, dual motor Wabco/Meritor brake system, all wheel air ride, 19.5" rims)  Cost was $65,000 running off the trailer.  There was reduced space on the interior of the GMC body because of the huge drivetrain-- I built a 23' and a 26' version, the 23' version cost well over a quarter of a million to build, the 26' was pushing $400,000.  The coaches ended up expensive, impractical and a morphodite from Hell with Workhorse closing up, now I have no idea who would work on them!
 
In the end, how many weekends do each of us have left to mess with this stuff.  You should take the time in your life left and just get in the seat and go!  When we are gone, the coach will be left and the next guy can screw with it if he thinks he has the time.  It's fun to think about but in the end, isn;t having a motorhome all about using it?  Many never do and that's why there are so many older motorhomes with low miles.   I want my motorhome to have a crap load of miles on the odometer when I am done with it.  I want the next owner to say I did a good job at keeping the beast together and I drove the wheels off it.  I think that's the best anyone could say about my motorhome.
 
Until you and I don;t really care, the drive train in our GMC serves us well, there are parts to fix it and it's not too hard to work on, what else do you want?  Speeds on the highway have dropped from the good ole days and with the price of fuel, going 60 MPH will give you about as good mileage as you can hope for.
 
So dream on, talk about all this but think really hard before you jump in the pool-- I already have prooven it's just not the right way to go,

I don't know.  Short of a total computer controlled engine and tranny I'm not sure there is enough of a ROI.  The 455/403/Caddy engines are just rock solid pushrod engines.

Yeah, the new stuff has all sorts of fancy controls (that I can't work on or even understand)but guess what?  12500 lbs with the frontal area we have at 60mph ain't ever going to go into 'supercruise overdrive' even if we had a tranny that had it.  A nice Allison tranny and new turbo diesel could be good but face it, you're talking cubic dollars.

If you don't want a real GMCHM, you could just buy an SOB pusher and put a GMC body on it... 8o .  Might be cheaper in the long run that trying to engineer and fabricate a complete new powertrain.  I've got a friend with a 40' Holiday Rambler Cat Diesel pusher that gets about 20....  It's a pre-slideout generation and they are cheap used...under 50.

Sure you could do some stuff with a new engine, make a new chain drive, adapt to a new tranny and rear end but you're going to spend a year and $$$$ doing it.  I've got the equipment and skills to do it but not really the years left.  Plus it would get into your living space....and never have a positive ROI.

How many miles do you have to drive at 12-14 mpg (I'd be surprised if you could get much more) to justify spending even 10K as opposed to 8-10mpg with the stock setup???  I'm too tired to do the math but it's certainly more than I'll live long enough to drive.

I think I'm with Gene on this one.

Good one Jim. I kind of thought our next move was reworking the space
shuttle. These coaches are what they are.
If you want Hi tech buy a new Mercedes Benz Sprinter and have at it. We
bought our coaches because we can work on them, get them fixed easily,
and get into them cheaply. These are old technology dogs and they work
as they were intended, and do it really well.
My new one I am working on was bought for that reason. I put a good
sound Manny Tranny in her, a rebuilt 455 with carburetor, the new one
ton front end, again for ease of service. I will rework the inside to
my taste and have a good time with her. Most importantly I hope to have
less than $15,000.00 in a good reliable and easy to service motor
coach. I think if we have good ideas for refining the existing beast
let's do it for sure but not just to do it because new is available. I
was a remodeling contractor for 40 years and my favorite and best
working tools in my shop are my old, cast iron tools. They don't blow
whistles or ring bells at me but they do their job really well and keep
on giving more.
Let's treat our babies the same way. If you have a good idea and it
will work with what we have let's do it. Some body has already invented
the wheel and it seems to still be working pretty well. Just my thought

Hey, Marcel is an excitable boy-- and really nuts over his GMC in fact he got used to and bored with his stretch, nothing more to do to it!  So what do you do when that happens?  Get another one and work out your frustrations on that one!  There are though a few things that I have to explain on his comments:
 
Don't think he is looking to top the quality of his current coach for a total expendature of only $15,000, some of you lurkers I bet raised your eyebrows on that one.  No, that's money out of pocket plus he's been getting smokn deals on the coach and pieces/parts going into it.  You guys say you do the work so that's free-- so just how many more weekends DO you have befor your job will be pushing up daiseys?  Time has value, yea Marcel loves this stuff and he certainly has the interior thing down pat with his specialty construction background so what is his expertice worth?  So don;t get excited thinking he's figured out a way to forgo the laws of nature. 
 
It's true that if you love the chase that you can save money from your checkbook but there is a value on his expertice.
 
The thing I think Marcel was pointing out is that he's had a while building up and driving his other GMC to figure out which options are value added and which one cause liability.  I will bet you this next motorhome will truly be a rock solid machine, will be outfitted with the things that matter and will do Marcel's bidding to the T's.  That's what I call a well built coach, time and thought will come together.
 
All of these things are fun to discuss and who know as in my case, once in a while someone might get off the porch and invest to try something but you gotta remember what the reason is that you have a GMC in the first place.  I feel it should be to use.  Some use them as an object of their frustration and that's fine too but remember there are different objectives thus there are different things those 2 people might consider doing to their coach.  If you have a work horse for the ranch, you don;t set him up with a show saddle-- that kinda thing.  Don't chrome plate your frame unless you intend on sliding a mirror under the coach to show it off and you certainly don;t need chrome there to make a trip cross country!
 
Don't create a morphodite if you intend on driving it places you have never been, who knows what support group you will find there.  It will be time consuming and expensive having parts and expertice shipped in.
 
I just felt that was a good post, one that layed out many of the considerations for folks looking to get a GMC out on the road and reliable.  I tried the diesel thing, did it the best way I knew to keep it reliable and maintainable-- it was a very expensive and unrealistic project but it was really cool so I guess that was a success  If that is success to you go for it, if you wanna drive one of these classics right now, forget about all that stuff because until most of us will not care, gas will be our fuel source and the original drive train will be the most cost effective.  My feeling on the subject,
 
Jim Bounds

how about this for a crazy idea that might work. Use a Corvette transaxle, 1/2 of an off road transfer case (to reverse the direction) and almost any choice of motor. Might be higher than our setup but you could have a modern electronic trans that would handle the torque of a diesel. :)

Holy crap, now that's outa the box!  Talked to a guy yesterday who is considering a coach that someone has put a Merceded turbo diesel with some wild front drive transaxle in.  Says it's the same motor in a Sprinter.  Man, I don;t know who or where you could get THAT worked on!  I'm determined to drive my 350 home this evening, get the kids off the sidewalk, I'm comn through!

If it's the inline Sprinter diesel, run like hell in the other direction.  We're on our third motor in two of them, courtesy of MErcedes.  Supposedly the new V6 diesel does better.  I've no intention of finding out, we will revert to Econolines in that market.  They say the trouible comes from the engine control system, - the wastegate doesn't open.  I don't need any more.

I have an extremely low mileage 8.2 liter Detroit Diesel Fuel Pincher V8 engine if someone wants a really big project. I starts up so quickly you can hardly hear the starter motor run. Half a revolution and it is running. They are claimed to be very good on fuel consumption and were used in school busses, commercial trucks and large boats.

I have no idea what you might run into adapting this thing to a TH425, but it has 500 ft-lbs of torque and weighs 1100 pounds. The weight alone would probable be a deal breaker. I doubt if there is any diesel engine of 500 cu in that is going to weigh anywhere near what an Olds or Cadillac engine does.

Since I have a lifetime supply of Olds and Cadillac engines I have no interest in diesel powering a GMC myself.

> I clearly need to get busy and stop thinking of nonsense. All the discussions I've seen about Diesel engines, vortec, etc also bemoan the lack of a modern transmission. It seems to me that part of the problem is that we keep thinking of the drivetrain mounted conventionally and not transversely. I suspect a transverse setup would eliminate the oil pan issues and open the door for a larger selection of power plants and transmissions.

The major problem is getting a steering system across and over a transverse powertrain.

The ongoing notion of "torque is what you want" really has no engineering foundation. HP=T x RPM /5252 so you can't have one without the other. The real issue is what the torque curve looks like. Also, the old notion of "there is no substitute for cubic inches" also has no engineering foundation. Lot's of torque that starts at 2000 rpm and stays flat till 5000 RPM is now normal. Given all that, a nicely refurbed 403 or 455 is still a nice engine for our usage.

No it doesn't. I am referring to car engines where high revving hp is not
what we want. (Think Honda or Toyota in civic type cars here) Torque motors
like the 455/ Cadillac 500 make torque at a much lower rpm and often has
less hp to boot.

your math may vary, im no engineer, I am in Psychiatry. lol

[IIF][/I] i decide to do anything more with my coach, since I need to do something I may revisit my proposed extended upper deck concept and use the space for a more modern drivetrain like the later Revcons and the Duramax FWD setup used. I'd even consider a Ford Drivetrain.

http://www.gmcmhphotos.com/photos/it-has-begun/p27836-split-kitchen-extend.html

This diagram allows for nearly anything to be put under there, and move the genny forward. Of course If I do any of this, the Bath module will be moved forward and a better layout for the rear bed would be implemented.

Its a big IF :roll:
