Yes and No.
Well I looked at all of them and in several different floor plans. The Synergy seems to be the sharpest version in the combination of length, interior and exterior providing you buy the full paint Ming Blue. All come in 4 different floor plans. I was going to recheck all the features of each before answering here completely but Thor has this new website and it's not working correctly right now. (oops) The biggest differences I noticed outside were the backs. Models with no slide in the rear of the coach have a more modern tailored looking back design. Basically they all seem to be the same just different based on color, cabinetry, floorplan and cost. You can buy the exact same coach for $140,000 or $78,000, it all depends on how smart you are and how much of your time you invest into the purchase process.
Hope this helps.
