There are a number of good brands. You mentioned some and I am sure that others will mention more. We have had a Lance and that was a good unit, we now have an Outfitter that we both like, its different but it works best for us. Since you want to use the camper in the winter then look for a rig with a winter package. In some respects you can insulate a TC for winter use and remove the insulation for summer.
With a 3500 you have lots of options. One thing to think about is the height, if you go hard side low hanging branches will not be your friend.
A TC does have a lot of convenience and mobility. That is why we went back to a TC after bigger rigs. We also use a TC much more than the other types of rigs.
Good luck.
