Don't know the second model. I have the 2007 Tropical LX. It is a great coach and the engine has handled anything I need it to. If you have specific questions I will try to answer them. 2008 was the last year National built coaches and some may have different available parts (not sure of this - just read on other forums). Thetwo slides in living room makes a nice large living area.
