Re: 5th wheels
We went with Glendale, but it was before the Titanium line came out. We have a Golden Falcon 40' /3 slide, I believe the Golden Falcon is now only made as a park model.
This is our first RV. The main reasons we went with this model are 1) my husband liked the way it was put together, as a welder he looked real hard at the frame
2) Being made in Ontario, it seemed to have the best insulation at the time we were looking, and 3) My husband is 6'2" tall, I wanted to make sure that he could walk and stand upright in every room in the camper. The ceiling hieght in the BR is @ 6'7", the is the shortest area in the whole camper (except for in the slide units, where you are usually sitting).
Make sure you get the bet that you can afford, as far as quality and comfort (including insulation factor), don't go too long because you may then have problems finding places to park. We have had that problem a couple of times, 36' seems to be no problem. And, make sure you have the correct hauler and hitch.
Our unit weighs @ 16000 and the dealer was going to give us a 15K hitch to pull it with, I made him get us a 20K before we would close the deal and get the camper off the lot.
We now pull it with a 2000 F550 deisel and 30K hitch.
