We pulled our โ31 QBH out west two years ago and took our grandkids with us. We took a month to cover just shy of 7000 miles as we live in Portsmouth, 100 miles south of you.
Are you taking kids, pets, spouse? Each adds a degree of complication and due consideration. Here is what we did.
Consider getting a National Park Pass. IT will save you money after about the third National Park you visit. Start getting reservations now. The campgrounds fill up fast and many will not accommodate a long camper. Measure your camper to get the length as sometimes the name in feet is misleading. Outside of the National parks are campgrounds that will accommodate longer campers.
Completely service the mechanicals on both the camper and truck. Being a newer unit the camper tires should be OK but get the wheel bearings greased. On the truck get the brakes and brake lines checked, all fluids changed, (motor oil, front and rear diff, transfer case, trans fluid coolant) and carry extra oil, coolant and trans fluid.) Get a way to change a flat on the camper and practice it before you need to do it. There are a lot of posts on this.
Go through the camper and get rid of unnecessary items, like the third crock pot, or more chairs than you have people to set in them. Just cause you have the room doesnโt mean you have to take it. Youโre within the limits of the truck, but more weight when not necessary is wasteful.
A good investment is a means of monitoring your truck vital signs in addition to the factory gauges. You especially want to keep an eye on the EGTs (exhaust gas temperature) because many of the grades a very long and the temperatures can creep up before you realize it. I highly recommend an Edge Insight. It is much better than factory gauges and you can keep track of more vital going on of the drive train, and if you throw a code it will tell you what the code is and allow you to reset it.
We have an auxiliary fuel tank and that was a big asset having 80 gal. plus of fuel. Keep a roll of gorilla tape and not all the tools from the garage but enough to do minor fixes.
Maps and up to date GPS, worth their weight in gold. Our itinerary was fairly flexible and there were days when we went 500 miles and other days when we went 200. We had in mind what we wanted to see. I think we went to 8 National Parks on our trip. My bride kept all our reservations and the like in a binder.
Take clothes that will let you be comfortable in anything from 30ยฐF to 110ยฐF, and sunscreen and hats and sunglasses.
Have at least 2 extra sets of keys to the truck and the camper. A set for each adult and a set to hide on the camper and the truck.
Just a few thoughts.
Above all take plenty of patience and maintain a sense of humor.
