You should be able to tow the TT with that truck, but if you are buying a new truck, why not just step it up a notch and buy an F-250? That should set some of your concerns to rest. Just make sure that you buy one with a trailer tow package and then buy a good WDH with four point sway control. I have a Sierra 1500 towing about 7500# with an Equalizer hitch. It tows the trailer very well and gets good gas mileage, but if I had bought the trailer first and truck second, I might have elected to buy a 3/4 ton. You can tow a lot with a half ton set up with trailer tow package and good hitch.
