I have a Fleetwood Expedition. Its a 2001 Model. DP with Cummin's engine and Allison Tranny.
We have fulltimed in that same MH for over 11 years and have to say, for about the first 10 years it was really maintenance free except for PM. Trouble free miles could be expected every time I pulled the jacks up.
For the last couple years, things are starting to show wear. Yeah, the diesel will last perhaps 300,000 miles. But all those extra pieces that are attached to the engine are wearing out. The fan fell off. Replacement for it and belts and hoses $2,930.00. Plus a wrecker tow for 7 miles. Thank goodness for Coachnet. The fuel pump failed, this time 90 miles on a lowboy, again, thanks Coachnet, but the simple replacement of a fuel pump? $560.00.
But...I wouldn't trade the ride and quietness of travel for anything else. I have no plans to trade, its still a very reliable MH.
