This coach is in an overall very good, well above average, ready to drive, ready to camp condition. The exterior is in excellent condition and was treated to a tasteful, modern and expensive ($20000) paint job in 1999. It has been kept inside most of the time since then and still looks great, even up close, really. There is no fading or clearcoat peeling. You could shave in the bumpers if you need to. There is no fogging in the windshields. It has modern tinted living area windows, Aluminum wheels, Zip Dee awning, modern head and taillights. I just put a fresh ceramic coating on it. You will never have a problem being accepted in a RV park with this 50-year-old motorhome.

All the mechanicals on this GMC Motorhome, both chassis and coach, are now once again also in excellent ready to use condition.

I will rate the interior as fair to good. I bought this coach as a stalled interior remodel project in August of 2022. The remodeler passed in the middle of the project, and it then sat untouched in a cooled Arizona garage for 6 or so years. I finished several of the individual interior projects and returned it back into a completely usable condition, but did not complete the entire remodel as planned. The PO removed the original dinette and replaced it with a big screen TV on a retractable frame in a custom cabinet. The TV install has not been completed, but I took the brand new but 8-year-old tv into the house and it tested out fine. The cockpit and rear bedroom curtains are old but fully functional and the living area Venetian blinds could be dressed up with a set of valences. I have had a lot of compliments on the interior and tv cabinet, but personally I would prefer a dinette. For that reason, I bought another dinette but have not installed it. I see 3 options for the interior. 1. Use it as it is. 2. Finish the TV remodel as planned. 3. Reinstall the original dinette. You decide. I can include used TV antenna equipment and/or used original interior pieces with the sale.

Not wanting to risk damaging it from a dry start with old fuel and oil, I had it towed to my house where the old fluids were drained, and new fluids installed. The old spark plugs were removed and the cylinder walls lubricated with fresh oil, the engine was then turned over until good steady oil pressure was shown, new plugs installed, then started. It ran well, but instantly the expected problems that come with a 50-year-old motorhome that’s been sitting idle for a while began to reveal themselves. It had a blown exhaust gasket. I’m a FAA certified Airframe and Powerplant (A&P) mechanic as well as an Airline Transport Pilot (ATP) and began to treat this motorhome project much like I would an Annual Inspection on an airplane. My squawk list has 235 items on it that have now all been corrected. The list includes everything from simple loose screws and burnt bulbs to more serious items like the blown exhaust gasket, tires, batteries, shocks, airbags, CV axels, etc., etc. Now EVERYTHING has been tested and works (except the trip odometer) and after 1000+ miles of testing and actual camping the motorhome is once again roadworthy and camp worthy and ready for use. There have been only 2 previous owners of this motorhome before me and they have used it, enjoyed it, maintained it, modified it, personalized it, and completed MANY beneficial upgrades.

I keep a logbook, much like an airplane logbook that includes things needing to be done and things that have been done. There are 235 items currently on that list that have all been corrected.

I've got a '72 P337 that I think is pretty cool but I'm getting a little long of tooth for flying. Might be of interest otherwise what are you looking for in plain old cash?

The P337 is a rare and interesting airplane for sure. It's also a practical traveling machine, but I already own a practical traveling machine, a PIPER Arrow, not as fast or comfortable as the P337, but more economical. I also own a Culver Cadet project I haven't started on yet. I'm looking for something funky and fun like a Seabee, Lake, Waco cabin, etc. I will take plain old cash also. I'll PM you with contact info.

Fair enough - it's along trip for us down your way to look it over but it sounds pretty good. I have a little cash but think I need some kind of number to consider whether I want to make the drive. There are a couple of units up my way I've been looking at but yours looks to be better if I can swing it.
 
Ok, I'll get to work on it after the holidays. We have a micro/mini car get together on the 15th we are working on now

Congrats Louis. Somebody got a good one.
When we got home from Traverse City the NOS airbags I installed had gone bad and all the freon leaked out of the AC compressor, so I reinstalled the old bags (which actually look really good) and dropped the price quite a bit to compensate for the new issues. Even still it's a very nice coach and will be even nicer when they install the upgraded systems.
 
Louis - got back a little late with headlight quitting had to wait for daylight. Not a problem got a good nights sleep. Very comfy. No other issues. Got home and manual says there's sort of circuit breaker at the light switch that should reset after 40 seconds if there's a short. Started poking around - found nothing obvious then
wife came out and said headlights were on so maybe it reset. Don't know and do hate itermittents but I'll fool with it some more. Otherwise both very happy with the buggy and appreciate your help and all your work on those several hundred squawks.
