Really impressed with some of the adventures truck campers are able to go on. Are there makes and models that could be carried on the bed of a Toyota Tundra? Happy Camping!
One quick word of advise, don't believe the dealers claims of what will fit on a half ton truck. Check the capacity of your truck. Then get the wet weight of the camper you find and add at LEAST 500 pounds to the camper weight (to allow for camping gear, food, etc.) to make sure your truck will be able to handle the weight. Capri campers seem to be popular with people with trucks with lighter capacities.
