Last week, my wife and I bought our first Motorhome. We pick it up Tuesday. Its not what we expected to get when we first started kicking around the idea of a motorhome. We bought a 1978 GMC Royale. Its in REALLY nice shape, no rust and mostly original. The one negative to it is that it has the Olds 403 small block instead of the Olds 455 Big Block. Anyway, here are a couple pics...

What made us go this old? We looked ALL summer at motorhomes. Its one of the reasons I haven't been on much. I've been focusing on the motorhome search mostly and just driving my jeep. When we started out looking, we were looking at Class C's. If we wanted to spend 60K+ on a coach, that would have been fine. However, since this is our first camper of any kind, we didn't want to jump in that deep yet. So, we set our budget to about 20 grand. We looked at a bunch of CRAP. I didn't want a constant project and it seems "modern" RV's are constructed from Cardboard, Staples, and pressboard. I saw more leaky roofs than I care to count. Plus, the tow and load carrying capacities were not great. They are not built on heavy duty truck frames, so the house portion of the coach eats up all the GVWR. We started looking at Class A's. We also increased our budget, begrudgingly. We were still looking at crap...still stuff that needed work and the thought of driving a "bus" scared my wife.

We had seen a GMC motorhome on Craigslist at the beginning of our search. I've always liked them so I jokingly said we should get one. That goes against the whole not wanting a project idea...so it was a joke to start. However, as our search changed, the idea of one of these started to make more sense. The are much more van like than a typical Class A, so my wife isn't afraid of them (Big Plus). They are 26 feet long, 8 feet wide and only 9 feet tall. We were going to end up doing work on a coach anyway, so we figured we'd get something cool that we can build value in. There is a HUGE community of fans and supporters for these coaches (like for the wrangler) so parts and knowledge are readily available. Finally, They fit our budget. So...we got real serious.

We found this one about 60 miles away. Its nearly ready to go. Its will need tires (they are from 2004!), the generator doesn't start, it has leaking exhaust manifolds and an oil leak somewhere. That's it for the necessary repairs that I know of right now. We'll see what pops up on the 60 mile drive home. The common rule of thumb for a ready to camp GMC is you'll need 25-30K to get something reliable and livable. We bought it for $15,000 and I figure I'll spend another 2K on tires, the gen set, manifold gaskets, and a full fluid change. Feels like a good deal.

Since this season is just about over, I won't do anything quite yet in terms of a toad, but I DO plan on setting my wrangler up for Toad duty. I'll need to tow 4 down, since the GMC isn't all that powerful...I can't pull a trailer AND the jeep. As it is, I'll need to change out the final drive to a 3.73 or so (from a 3.04). For those of you who do, what am I looking for? I know @bobthetj03 tows.
 
I love the GM coaches. They were built more for luxury travel than live in camping. Your 2K estimate to get going may be a little optimistic, but when you get going you will have something special. I believe the final drive is on the front of these motor coaches. have fun - post pictures.

You are not joking here. I went in like a rookie when we bought ours and didn't know what I was getting really. Mine is a 2011 Class C and is built like crap. The fixtures, cabinets, and interior components are garbage. I've had to reinforce the bed frame, kitchen sink and counter top, dinette, and other misc things that are simply falling apart. I spent $1200 to fix the generator(oh, and it's broke again after this last weekend's trip to the Rubicon), reinforce the whole right side of the coach walls, I can go on. They are money pits, just like my jeep, but they also provide a certain freedom. I can take the dog camping, and we can go places I normally wouldn't go, so pluses/minuses to the whole endeavor.

Like you, I wanted a coach the wife would feel comfortable driving if she so desired, so we didn't really pay attention much to the Class A's. I didn't like how high you sit in them, so it was a funny feeling.
As far as towing, make your jeep as light as you can. Check CL for deals on tow bars. One with adjustable arms makes hooking up easier. I picked up a Falcon II tow bar setup for $250 on CL, and included the tow bar mount to the jeep.

Many states require supplemental braking for the tow vehicle, so check your laws in your area. It's a good idea to have one for insurance and liability reasons. I picked up a Brake Buddy, also a CL deal, for $300, but had to send it in for repairs when it decided to lock up on me on the interstate. That was fun trying to pull to the shoulder on a 5 lane freeway!
I went with a plug-n-play harness from Hopkins for the lights. Super easy to install and has worked flawlessly.

Just got back from a 400 mile trip to the Rubicon Trail climbing from 70 feet elevation to 7200 feet. On the steep climbs I was able to maintain 50 mph. It's a Ford E350 chassis with the V10, and surprisingly, is the best part of the coach IMO. Only thing I've had to do is change the oil.

My RV is a 2001 Alpine Coach. I bought it 2 1/2 years ago. Before the coach, i was riding motorcycles and had a couple of toyhauler trailers. I use a Ready Brute Elite towbar. I picked the ready brute because it uses surge brakes. My towing lights are battery operated wireless (I didn't want to modify my Jeeps wiring).

You said you need an additional tow bar on the jeep. Does that mean you can't use the recovery tabs on your bumper to hook the bar to? It seems like the Shackle Mounts would be a perfect place to connect a tow bar (as long as they matched the spacing on said bar).

I'm glad there are options to not have to cut into the factory wiring. Thanks for the heads up!

Nice Rig!

Well, You were right...LOL.

What started as a "Tune-Up" has turned into a full top end rebuild. As you can see, the distributor is rusty. The advance was so stiff it wouldn't work. Its moving now, but I bought a whole new distributor. I knew I needed a radiator, so when I was pulling it out for a re-core, I noticed that the oil was slightly milky. Decided to tear it down to make sure things are OK. Turns out the intake was probably leaking. Head gaskets looked good, but the cast iron intake manifold has seen better days.

This shows a crack between the two secondary bores...This one isn't really a big deal. Seems all Olds 4 bbl manifolds have it.

However, the careful eye will notice that there is a crack on the outer wall of one of the secondary bores too. This WILL create a lean condition...

So I have a new aluminum manifold on order and the Heads are out to an engine builder for a quick check-up and valve job. I also installed a new timing chain, water pump, and fan clutch. I haven't gotten to any of the other stuff that needs attention on this pig. I think it may be a bigger money pit than my Wrangler....and that is saying something!

I use the shacke points for the safety cables. I had some brackets made that bolt onto my bumper for connecting the towbar. Most of the aftermarket bumpers are not manufacturer approved for towing from the shackle points. The second picture shows my brake cable (surge brakes) and the emergency brake cable (from the red block). Here is a link for the lights I use: https://www.etrailer.com/Tow-Bar-Wiring/Pilot-Automotive/NV-5164.html

I love the old campers/RVs. I take pictures of them when I am out and about. It's been my experience that every camper is a project. If you are lucky, the problem is something you can fix yourself. :)

If you're interested in following along, I am doing a blog type site here...

https://mikehiler.wixsite.com/ourgmcmotorhome
I try to update at least once every couple of weeks...with the goal being every week. Its hard right now because I'm still in teardown mode. It should start going back together soon. Rather than posting just to post, I try to get some real content, so its a bit more sporadic.

Back on board! That’s one hell of a rig! Welcome back. I’ll be tuned in to this one.
 
This is our set up. Taking a break on our trip back home from Moab this year.
So nice to be able to just stop anywhere, have lunch, take a nap what ever you want to do, spend the night even.

That's a classic "tune-up" right there Mike! I've had that happen more than a few times. See something cool, convince yourself it's only going to take some minor top end work, next thing you know the body is off the frame and the bare block is sitting in the middle of the garage and your wife has no place to park inside.
