When I bought my (former) Cruise America rental it had 109,000 on the odometer. I've been fulltiming in it ever since. Since it was a fleet vehicle I did not worry about the high mileage. What did give me pause is the fact that no service history was provided to me. I solve that by establishing a new service baseline. I had every single fluid and filter replaced - including on the generator. Since then I have had the spark plugs and spark plug boots replaced, and the upper and lower ball joints replaced.
To assist with flat towing I had a rear trac bar installed, upgraded the front sway bar, and replaced the OE steering damper with a Safe-T-Plus steering stabilizer.
