I have a 2008 Dodge Ram 1500 with a 6 ft bed and airbags. What is the max length of truck camper should I get? And will this particular truck handle the camper? Thanks for any input!
Bigger is better in terms of the truck, but if you have the truck then there are campers that fit short beds, and those that fit short or long beds and will work on your truck since it is equipped with airbags. We purchased a Palomino 1240 and installed Timbrens and it rides beautifully, there are even lighter models in the backpack line. Also Four Wheel Drive campers specialize in light campers that easily fit a 1/2 ton, but they are pricier than the Palomino. Good luck!
OP, sorry to say but for all but the LIGHTEST units (generally a less equipped pop-up without a bathroom) 1/2ton trucks and truck campers don't mix well. You truck can tow MUCH more then it can carry, so a travel trailer might work out better depending on your exact needs.
More important the length is the weight and is it made for a short bed truck or not. Your truck won't handle the normal campers for short beds since they are designed to be hauled on a much heavier 3/4 or 1 ton truck.
Start with the GVWR for your truck that should be on the inside of the driver door pillar and subtract the weight of the truck to know what you have to work with.
Definitely get one made for a short bed, as the center of gravity is further forward. Those are usually limited to 9' and less. Less is better with a 1/2-ton.
