Refresh my memory please-GMC motorhomes
I've been flirting with buying a restoration GMC Motorhome that's nearby. Please refresh my memory- was it the handling on the road that was difficult? Here's a link to what they look like http://gmcr...

Handling on the road is one of the things they do pretty well. What is said is that they are much better on the road than they are at camping. That is probably referring to the fact that you have more beds than you do storage or bathroom space. Along those lines, most have a wet bath, which means you shower over the toilet. There are rear bath models that have a separate shower, or '77 or '78 Royals that have a separate shower, but those are hard to find and one pays a premium for.
The drivetrain seems to survive as well as anything from that era, except for the front wheel bearings which require attention about every 30K miles. Probably the best inexpensive solution there would be to cryo the spindle, the hub and a new set of bearings. Cryogenics equalizes the hardening process, so you don't initiate pitting on the bearings. Secondly, it stiffens the metal, without making it more brittle, which is why you need to cryo the spindle and the hub to reduce bearing walk.
When I was shopping before I bought the Revcon, the GMC I looked at had some sag in the side walls, which meant the entrance door did not seal along the top or bottom. The side had also pulled away from the interior wall. I have since read that this is not totally uncommon, but apparently not universal either. Something to look at when you are buying. Some other issues to look at would be the condition of the plastic cabinetry. Plastic of that type tends to get brittle with age and crack. Look around the interior windows for wall rot from the window seals leaking. Nothing insurmountable, but all factors in what level you want to restore to.
