I never have full timed but my DP gets used almost every week and now has about 105,000mi on it. I looked back through my records and in the past 5 years I have driven it almost 50,000mi towing a 32ft trailer. Repairs other than once a year complete service has been leveling jack springs, wiper blades, step motor, a radiator, and a radiator hose. Radiator didn't fail but I replaced it before it did and it cost $1800 I think. I fix what needs fixed but this is a high end unit so maybe its built better. I sure don't baby it. Keep looking!
