Hi Fred, if you only intend to pull that Tradewind-I don't know the weight for sure but believe they are quite a bit lighter than the newer AS's-then you should be fine.
If you have anything bigger/heavier to pull I would look at a 3/4 ton or at least a lower rear end gear ratio- 3:73 or 4:10 would be best.
The only concern I have about that particular TV/TT combo is the 3:55 rear end...a little high for towing.
But again, with a light trailer and load (under 5000# or so total) you should be fine.
