I had a TT type TH and I will never have one again. First thing to take into consideration is the TW of the trailer will be much more than your typical 10-12%. It will be more like 17-20% before you load any toys in the back. They need to do this in anticipation of the load you be hauling behind the rear axles. So keep this in mind if you ever decide to go camping and not take any toys with you. That would pretty much kill your payload and be sure of a horrible tow experience.
I had a Ram 2500 CTD pulling a 28ft Desert Fox travel trailer type toy hauler. It was technically more than enough truck for the weights however I could never get the trailer balanced and it became such a PITA trying to that I eventually sold it after so much disgust while towing the **** thing. Your weight and balance leaving for the trip is going to be different then the return trip. Water, black tanks etc are going to disburse weight differently etc.. For the two years that I owned that trailer there wasn't one time towing that it didn't sway. Horrible horrible experience and it wasn't for the lack of knowing what I was doing or trying to balance the trailer to achieve the 10-12% TW that would allow for a decent towing experience.
If I could give anyone any good advice or recommendation it would be to RUN away from a TT TH and instead invest the money the first time on a good FW and truck setup. Believe me it may be more upgront expense but it will still be lest costly then finding out you rather have a FW!
So now I got my FW TH and couldn't be happier. No sway solid ride empty or loaded to the gills. First trip we took was actually empty and ran 300 miles out into a very remote part of Montana and for the most part didn't know the trailer was behind us. I couldn't be happier with the towing experience of the fifth wheel.
So - if you proceed with the TT TH .. take some time and research what I am saying and what other similar owners have said. Lots of horror stories with TT TH setups (excluding the little popup style with atv ramps on the front.)
That's all I'm going to say.
