Sorry to say but I agree with others. Your truck is too small. Your truck may be rated to tow 6500 pounds but that is in the best conditions (flat bed trailer or boat trailer)and RV travel trailers are not the best conditions. The wheels in a TT are further to the front than a boat trailer causing a lot more force for sway and the high walls creat a lot of force against the air and wind.
Also your TT is very long while your truck is short and light. I would at a minimum ensure you were fully set up but I would look for a full size truck.
