As has been said many times in the past, if you find, and you will, a rig that allows you to tow yout truck and MC, and has the right floor plam, nothing else matters. At least for now:).
I have found since we bought the Adventurer, the RV is bigger than I am. DW won't drive it and I am tired of doing everything
I need to do to keep it like new. It does have so many more features than we need now but wanted 5, 10, or 15 years ago, plus the $175 a month storage fees we didn't have with a smaller rig.
There are Bs out there that are good for a 10K mile trip and "A"s that are over the top for us but may fit your needs. It really is hard to say what will work for you.
Set your priorities and look, look, look. There is one out there for yoyu.
