Just a story about what I figured out a few years ago when I was shopping for older motorhomes. They aren't always what they seem. I was looking at a coach that seemed in pretty good shape, drove nice etc. This was an aluminum sided coach. Upon further inspection I noticed some pin holes in the siding under the windows. It got me to wondering about what was going on. I stood back and looked, the holes were in going down at about a 45 deg angle toward the back of he coach. I went inside and pulled the couch away from the wall and there was obvious evidence of water damage. What had happened was the window had leaked and the water incursion had started to rot the side of the coach. My point being that if anything seems out of sorts or there is any evidence of recent repairs look for something that may have caused that. Especially look around any roof or sidewall penetrations. When you go to look at the coach don't tell them you're coming just show up. Insist on starting the coach when it is dead cold, that should show up any hard starting issues with the motor. You might also want to open the engine compartment to see if the engine is warm. If it is the coach may have been started to hide cold start issues. This isn't so much of an issue with fuel injection but it won't hurt to see. When you take it for a test drive put it under hard acceleration and see how the transmission shifts. A good transmission will have a nice crisp shift under heavy load, a worn out transmission won't. If the shift is sluggish it's no good. Also look at the engine oil and transmission fluid. Most folks change the engine oil but neglect the transmission fluid. If the transmission fluid smells burnt the trans has been abused. I would also ask to see the manual and use that for your guide to check out the coach. If you see any wires spliced with butt connectors I would want to figure out exactly what they go to and why they were cut and spliced. Also look for any abandoned wires, this is a sure sign of electrical issues in the past and the wires were replaced with something else. I would also charge the plumbing system and ensure that the faucets don't leak (but this is an easy fix) but more importantly the plumbing itself doesn't leak. As to the price premium that's a decision you have to make, but if you want the best deal you have to be willing to walk away from it. This isn't the last coach in the world.

Basically, I thought the same as Brian with regards to the mileage and age of the RV.  That's only an average of 1842 miles a year.  As a general guideline, most with motor homes prefer to run their units up to operating temperatures about every month of so.  While an "exercise" trip of 50 miles every month wouldn't be as much as the average, I'd worry that some years might have gone without much exercising of the unit's power train.
