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...

'84 Tiffin Allegro M-31. Bought from the original owner with a blown engine (Chevy 454) at 79k miles. Piston came apart in the #3 cylinder. Put in a 20k mile 454 (1990 GM Performance engine, truck spec heads and cam, Mark IV block). Hoping for a few more years out of it.
