So much depends on what the expected usage is planned for. Full time vs short hops... We had our list of Must Haves and Nice To Haves. Selected down to three manufacturers with a total or 8 models to go out and look for. For 'us', your opinions do (and should) vary, I'll add a few of the Must Haves not in this poll:
-38-42' (we bought 40')
-CCR (help me on the buzzwards, brain fade - extra weight we can carry, we have 5300lbs more capacity (DW has 1800lbs in shoes alone
-Slide out trays on basement
-Two non passenger slide, or three with two slides in bedroom (we ended up with two slides on Driver side)
-Large galley (ours is bigger then most 45' RV's, DW wanted counter space)
-Non galley slide
-Good insulation value
-Silverleaf or equivalent
-Lighter color scheme
-Pre 2006 emission, with a bonus to (spread sheet weighted grading system) given to 2000-2004 engines emissions (2004 and before, we had a cutt of on this century, thus the 2000)
The one feature I wanted on my Must Have's that I could never find (Foretravel, Country Coach, Travel Supreme) was the self washing and waxing exterior option, and bug free front window. That would be a neat option to have...
I did really want a TRW or Comfort Drive type system. But the Mountaine Air on Spartan chassis coaches did not make it to our final cut. Nice coaches, but the models we looked into did not match what we were looking for.
Best to all, have fun, be safe,
