Sorry to bump an OLD thread, but we've driven just a couple of T/C's so far.. The first was a smaller Haulmark - 26' coach section, FL M2 "business class" truck. The build quality / fit & finish didn't hold a candle to the 2 Kingsley's we checked out. The Haulmark was brand new and squeaked & creaked more than the Kingsley that was 5 years old. (Yeah, Kingsley's are HIGH end, but it's what I've seen in person to compare)
But just from looking at how well the used ones hold up, the Renegade & United coaches seem to stand the test of time better than the Haulmark's, as well as having higher quality amenities and more "creature features".
Just my $.02 as an unbiased window shopper.
