Build Year and miles on your chassis
Our 2003 Dolphin is on a Workhorse W22 with 8.1 Vortec/Allison 1000 five speed transmission. It has 79,000 miles, of which about 25,000 have been towing a 1999 Grand Cherokee. I am hoping for 70,000...

2000 Itasca with a V10. It has 80,000 miles on it without any problems nor has oil consumption, mpg, or anything else changed that might indicate things are soon to give out. I expect it to last at least another 10 years and 70,000 miles. It does sit in a shed when not in use and gets Mobil 1 engine and tranny oils.
