I am looking at a 2004 Damon Challenger and need some help ! It has a 8.1 Vortec Chevy Engine. It is a 36' class A & I will be towing a Jeep Liberty. Is the engine strong enough to pull through the mountains ??? My 1991 Bounder 31' with a Ford 460 is terrible & it needs 93 octain gas. The Damon owner says it only needs regular gas. Any help please!!! Dean PS Is the V10 any better? Does Ford or Chevy have a better transmission ?
