I have a Ford 2003 E450 Class C Diesel. Its a Winnebago Minnie 24.5 ft with 7.3 PSD
Very rare Class C. Its in pretty good shape, not showing to much age. it has a
Gearjammer Under/Over Drive setup. Propane Genset. Mechanically have not really had any problems. 7.3 PSD has a great rep its only knock is that it's old tech, but it runs strong!!! Have upgraded to a 4" exhaust,installed an engine cover sound deadener and rearranged the engine and house batteries.
Moved 2nd start battery to step and went with one 12v marine eliminated the 2 6v gc batteries. Do most of the regular maintainence myself oil( 15qts oil & filter ) and brakes. There is a lot of talk about fuel mileage I get around 10 mpg towing a Subaru Legacy, get over 400miles on range. All in all very much Satisfied...
