I'm going on vacation with the family to Mt. Rushmore from Washington state borrowing a 30ft bumper pull camp trailer weighs about 10k fully loaded any one know what the hills are like to get there? I'm going to leave the slip tank in the back of the truck full of fuel in case I can't find a station selling fuel when I need it, just changed over to all Amsoil in the truck should be fine there, got new tires 5,000 miles ago and 2 spares for the truck and trailer any other thoughts on what I may need.
I always carry an extra gallon of coolant but that's cause my truck is a natural puker. Just make sure your factory jack is in good working order.
