I have a 2003 class A 29' Damon w/ the 8.1 workhorse (no slides). My wife preferrs to drive a class C , so we are looking into a new/newer class C in the 28'-31' size & I'm towing a 05 GMC Envoy XL (4600 lbs). The engine options seem to be the Ford 6.8L V-10 (305 HP)or the Chevy 6.0L V-8 (300HP). I'd like anyone w/ info on how these compare.
