Considering a New Tow Vehicle

1/2 ton sounds like it would do fine with what you have now, but if you plan to get a larger TT, I would look closely at the capacity of the truck you plan to buy. I loved my F150, the ecoboost was more than enough to tow my 5500 pound TT, but within a family of four, I was with 130 pounds of my maximum cargo capacity and even with a properly setup WDH it didn't feel safe. The good news is that you can get F150's in a wide range of cargo capacities, so if you go that route look closely and know your numbers when you shop. I upgraded to a 3/4 ton for safety and the prospect of a larger future TT.

I'm not the weight police, I just speak from experience.
