Rich,

I asked this question in the discussion group at the first international we attended only a little of....
The answer then was,"that very much depends on how you (plan to) use the coach."
Well we now know how we are using the coach, and the first answer is not at all use dependent.

First by a wide margin is the "Reaction Arms" on the four rear brakes. That changed things from trying real hard to make a controlled stop to nearly
the equivalent of tossing out a very heavy anchor on a short piece of chain..... (What that AH in the little car ahead just did is no longer a white
knuckle time.) This is a true and all time winner.

Second, but not all that close behind is the fly wheel trigger Pertronix on the Onan. It now runs so nicely that all I have to do is take care of it.

Yours is a 77, so you can't upgrade the distributor easily, but I put Pertronix in my '73 too and a (period accurate) Delta MkXb CDI and opened the
plugs up to 0.060. Makes for nice running.

Third, but very close to then second is the electronically controlled fan I have now not only comes on and off when needed/wanted but is quieter than
the stock.

I'm not really sure where this one belongs, but dumping the "Buzz Box" converter allows me to:
A - Keep the house bank both charged and
B - For years longer (Saves a lot of Money) and
C - Makes the required water tending much less an issue.

This last not count as a actual upgrade because if you are willing to put up with what is there, it can work. The Progressive Dynamics converter just
saves you time, money and work.

I don't have a macerator/pump, but my home dump is next to my driveway. Where it not, I might consider this.

For me, it definitely was the 3:70 final drive. No cosmetic changes, of
which there have been many, do much for the drivability of the coach. If
you enjoy yours more when it is parked than when you are driving it, than
that probably figures into what pleases you more, I guess. I love seeing
what is on the other side of that next rise in the ground, I love to long
distance travel.

I'm with Matt on the Onan Pertronix. Biggest bang for the buck so far. He
strongly recommended it to me, and im glad he did.

We use our coach for the kids (2&4), family visits and weekend camping.
Their comfort equates to my comfort. Therefore the installation of a
television, sound system and media server/wi fi that runs on 12v keeps them
quiet. A new AC that runs off of a 15amp circuit keeps them cool when at
homes lacking a 30 or 50 amp

Justin:

Considering how I like to drive it, the Fuel Injection is way up there, too.

How about three #1’s? Macerator. Pure Sine Inverter. Fuel Injection. In any order you choose.

Matt’s comments are spot on, too.

Floating the brake backing plates on the rear 4 wheels - what GMCers call reaction arms. Makes for safer stopping without flat-spotting the tires.

Interesting responces....our goal is to drive this unit....alot!! Lol....

Interesting that #1 so far is the macerator (which mine doesnt have).

The buzz box will eventually go as it drives my wife nuts but being a Hughes coach this buzz box has living area fuses in it unlike the GMC
setup.....going to be much harder just to swap without adding a seperate fuse block (not a bad thing i guess)

Reaction arms look interesting....trying to find a used set (im cheap and how much does this stuff really get used anyways) is gonna be hard.

Keep the info coming folks....very very interesting.

For me if forced to pick #1 it would be Howell Fuel Injection with EBL and its other bells and whistles.
After that the next best things, that I would hate to be without, would be in no particular order:
-Macerator
-Custom Instrument Panels -dash
-Automatic Generator transfer switch
-Alcoa wheels
-tankless water heater supplement to the OEM heater (makes camping at Walmart nicer)
-Samlex America (SEC1250UL) 50 Amp Battery Charger
-Samlex America 2000 watt inverter wired to key outlets via automatic switch
-Dave Lenzi's sensitized brake booster
-Progressive Industries EMS-HW50C Hardwired Electrical Management System
-507 TST Tire Pressure Monitoring System from Truck System Technologies
-Always on Backup Camera system with 3 cameras
-Bogart Engineering TC-2025-RV battery monitor

and dozens more.

Oh and one other thing. My new heated and air conditioned GMC Motorhome garage (still a work in progress but my GMC is now living in it) should be on
the list. No more working on the coach outside in all weather conditions.

I think the macerator is an easy go to for number one because it's just miles and miles ahead of using the big dump hose. It takes the worst part
about RVs and makes it trivial.

For a couple hundred tops it's a must do.

Not having had her that long, and still working out what I HAVE, my contribution is short. Haven't had the opportunity to do any of my own, but the
things that my PO did that I am grateful for....

1. Macerator - can't believe that a lot of SOB folk have not heard of that. Often get a strange look when I'm dumping, then occasionally wistful
when I'm done and pulling away and they are still getting connected.
2. IntelliPower Converter - I am in a part of the country that for 5-6 months, she has to sit (mountains of BC) under a tarp (no garage). With this
I can just plug in and the converter keeps her in maintenance all winter long. 2 springs in a row now, after 5 months of sitting, turned the key and
fired right up. No pulling the batteries (which I just can't do myself) or disconnect the negative and hope they still don't freeze up in the -35C
that can come (and does) or slog through the snow to plug in to charge them up once a month.
3. EBL EFI that I am still figuring out.

Wish list:
- reaction arm brakes
- 1 ton front end
- update the air-bags (haven't decided which system I would prefer)
- and, and, and....

Another thing that we like a lot is our Separett Weekend 7010, that I've
installed in our 23'.

Thinking about the fact that macerators are No 1, and we have the above,
it seems that taking care of dumping is the real issue :-D

Dave,
Ken slipped this down from the "Best Update" thread, I'm going to take you both back there.

I had not even thought about that. That was the end of a long development program for me that was all about stopping the alternator squeal.

When I found out that after two nights of dry camping with electric refrigeration the poor little supposed to be 80Amp Delco 27SI can do more than it
is rated to do if you have the GC2 house bank in the front and nice heavy conductors. (I actually measured 98+ with a Bell current probe and a Fluke
87 - in case there are doubts.) The simple fact is that an alternator for a 12V nominal system will destroy a single belt at a 100 amp load.

As this was something I was very well familiar with from the boat work of converting retired racing sloops to be Performance Cruisers. (They all
wanted more house electric.) I though long an hard about the cure that I often used then, but that was a programmable current limiting regulator that
sure would solve the issue, but they cost me about 400$us each. The new belt I needed anyway, so I bought 2 and a 10$ double sheave.

It was almost too simple to be listed as a serious mod.

For me #1, and second most expensive (the most expensive was the engine/transmission rebuild) would have to be the six wheel disc brake/Chuck Aulgur
reaction arm system. The confidence this system gives me in mountains (disc brakes) and city (reaction arm) was worth every penny.

There have been lots of others, in no particular order:

Engine rebuild with Jim B "Kryptonite" cam

Transmission rebuild with all heavy duty components

3.70 limited slip final drive

Solar battery charging

Dave Lenzi hubs, knuckles, bearings

Norcold 643.3 fridge

The list goes on and on.
