everyone, i need help with a truck/truck camper questions.

Ryan - while I appreciate your situation and multi use goals of your truck, I would have to say I wouldn't consider anything short of a single wheel 3500. Having had half, three quarter, and ton dually pick ups, the one thing I notice is each time I upgrade - I get a heavier truck. Each time I get a more satisfactory and safer vehicle. Could you get by with a 3/4 and a light camper, yes - but why cut it so close. Have some margin for comfort!
