There are (currently) three major areas of expertise covered on this site:
- Auto (vehicle) mechanics
- Auto Body Work
- Performance Engineering
The criteria I would use for all these questions is "Would I bring my [RV, ATV, trailer, boat, jetski, snowmobile, golf cart] to one of these experts to resolve my problem?" If the answer is "yes", it should be on topic:
- Batteries/Alternators
- Body Work
- Fuel Systems
- Engines, Drivetrain, Brakes, Maintenance, etc.
For the more home-y aspects of running and operating a motorhome, I'm not sure you will find the expertise you need here. Questions about furnaces, kitchens, plumbing, furnishing, trim, and the like are probably better asked on the Home Improvement Stack Exchange.
