Greetings and welcome to the forum. I would recommend a 3/4 ton van. After the 2 batteries, (about 120 lbs), you may want some water, (10 gallons is 83 lbs), add cabinets, food, camping equipment, and soon a 1/2 ton model is at it's max rating. Sure you can overload them a bit, but the brakes may not work so well.
