Buying first travel trailer...need advice

you are ok. 14000 gcwr-7900 trailer= 6100 - 5300 curb weight of truck = 800 lbs. you will only have capacity for 800 anything else you put in the equation. 7050 gvwr- 5300 curb of truck= 1750 - 800 tongue weight = 950. you have more payload remaining than you do combined capacity. Unless you pack the trailer to the max capacity and throw an atv in the bed of the truck you are fine. people will try to convince you that you can't tow at the max but they would be wrong. you will eat some gas and go slower but you will be fine. one thing to make sure you keep an eye on is elevation. your truck produces less power as you gain elevation. all this means is you will have to slow down. the truck will let you know if you are asking for more power than it can produce by slowing you down. if you have mountain passes in your route you may want to dump some weight i.e. water tanks on the trailer. i use a honda ridgeline to tow my TT. GCWR of 10,080 and I hit the scales at 9,600#. i run a max of 65 mph and don't pass up a gas station.
