We are in the same boat as you. We just brought home a new KZ301 bunkhouse, I am taking a break just now loading it up for it's maden voyage to Michigan. All I have done so far is hitch it up and bring it home. Tows great so far here in the flats of Illinois, tomorrow will be the first test for our family, we are very excited.
We chose this camper because of all the good things I read and because the local dealer has been wonderful. We have noticed only a few small fit/finish items so far and once we get a short laundry list of issues we will have them addressed at the dealer under warrantee .
Good luck to you on your move to the bigger camper and enjoy!
