Just a few things. Really this is our first 5th wheel and we really didn't realize the super depreciation. We wanted the automatic leveling system, solar prep, textured panel on fridge, we like where the electric hook up is on the side instead of the back like ours. Also hubby liked the fact there is a tube next to the dump valves to store the hose. And I like the medicine cabinet in the 2017, ours is thicker and we hit our head on it when trying to wash our faces. ok I know that's not a big deal but we plan on full timing in 2 years and we wanted a few of the up grades. But we will do it all ourselves now. Hubby is a jack of all trades. Tara
