Then take a ride over to Bill Penny's place, Truck Camper Warehouse in West Chesterfield right there in NH. Bill's got a fantastic selection of all types and models. Take a look at all of them and give yourself some better ideas on what you may want.
I agree. Make sure you look at used and new to get a variety of options. He will also make sure you have enough truck for what you intend to do. He won't sell you something that puts you way over loaded and not able to enjoy just to make a sale.
I really enjoyed my visit when I was in the area and had a great talk with him about several units. He had a bunch on his plate, but enjoyed talking so wasn't brushing us off to the side.
