I have no priors to compare to, but our 8310SS is awesome. Just towed it 2400 miles, and but for a few heavy crosswind gusts, often didn't notice we were pulling a trailer (almost 10,000 LBS loaded). As per most of the other comments, go with the floor plan you like. You are living IN it most of the time. When you are driving, I hope you are looking at the road rather than admiring the front, bug-smattered, end of your TT. And when sitting outside, I trust you are admiring the beautiful forestry, mountains, lakes, etc. or chilling with the neighbors and a few brews. Outer looks are secondary at best - jmo! And regarding gas mileage - it sucks no matter what! Pray for tailwinds, but plan for headwinds! Most of all - ENJOY!
