After the brand issue is settled, it comes down to inspection! Forget brand and realize all things only have one determining factor: good day, and bad day! So only a qualified inspection, from an inspector without prejudices, will be able to insure a quality rig!!!!
It might be prudent to point out, most owners can tell you, if honest, that there is no such thing as quality in the RV market!
The lesson here is, look at all makes! Find the one that is most pleasing to you! Look for anything that appears cheap to you, and determine if you can live with that! Then when you have come to a consensus you all can agree upon, call the inspector to find the stuff you didn't think of!
