dose the trailer have electric brakes? the truck can tow and stop that size trailer all day long. going to have a MPG hit but that happens anytime you tow. The big issue is the brakes stopping a 3K trailer (going conservative here) for a long trip will wear your truck brakes. If it has trailer brakes it will make life 1000x nicer towing and stopping it. When you load the trailer and set the ball just make sure the truck is level with the rear lift.
