1Fast: Contrats on your New Combo of TV&TT. Truck looks really nice and you must be excited. Put some miles on it before towing your TT any long distance, to let the engine break in some.
If the Truck doesn't have extension Mirrors, you may need to purchase the type that slide over the mirrors, so you can see along the sides of the trailer-when towing.
Also, when you hook the TT to your TV, practice some towing it around a large empty parking lot. Apply the brakes on the truck while going slow to see if you can feel the trailer brakes working as well.
I don't know how much experience you have towing with a Truck, but as said, plenty of practice, doesn't hurt for when You and Your traveling group go have some FUN.
There are a lot of Experienced RVers on this and other Forums, that can give you some great advice.
