Diesel miles

I have read diesels run 500,000 miles before any work on 80,000# over the road trucks. My coach only weighs in full tanks at 28,400, but is rated at 36K max. load and towing. Gas engines have a shorter life span in RV’s where often they are having to work hard all their life. Some say 80-100K is the life in an RV for gas engines.

On the RV forums new buyers always want to know about a high mileage diesel, like over 100K. Most often they are told, the diesel if serviced is not going to be the problem. It is usually the RV systems and structure that fails, from roof and wall leaks, and the results of driving the house down the road.

My two Foretravels were or are squeak and rattle free, one over 110K, the newer one over 95K. Everything still works like the day it was delivered.
