It seems like there is a conspiracy to make campers difficult to use. What a pain! I have had the same camper for almost 20 years and it has taught me a lot. I think the "center of gravity" issue needs more emphasis here, because it caused me more problems than I would have ever guessed. First, think of your truck. If it's a super cab with a small seat behind the driver, the center of gravity of the camper will be shifted back two feet. If your truck is a crew cab, the number is four feet. This means that the further back the camper is relative to the wheels, the more weight will be carried by the rear axle. For me, air bags and a rear anti-sway bar helped the most. Torque-lift tie-downs also helped with anchoring the camper. Then there's the length of the over-hang. If you have an 11 ft 6 in camper like mine, you have 3 ft 6 inches of over-hang in the back. Now you need a special tow-hitch setup if you want to tow a boat or other trailer. On mine, it's such a pain to disconnect that item, I never remove my camper from the truck. If I were to do it over again, I would go for a shorter camper, no more than 18 inches past the edge of the truck bed.
