Help with Weight of Truck Camper

Hello fellow campers!

I have a question that I would like opinions on - I am sure this tossed around a lot…

I have a 2005 Dodge 2500 with the 5.7L Hemi Head. Great running truck! Since then, I have added 5K Firestone Airbags and a Tork Lift tie down system. I have added a cold air intake with exhaust modifications. I have 10 ply tires, brand new and my next step is to buy a slide in camper. Per Dodge, the payload is ~2,500 lbs and with the airbags at 40 psi, I can probably go up to 3,500. I have a 19 foot boat I tow as well, not a huge boat but a fiberglass fishing boat that probably weighs in around 4K when fully loaded with trailer.

I am trying to think of everything I can before pulling the trigger on a truck camper to account for the weight and power. Knowing the above, what is the max weight you would put in the truck bed - wet weight? I live in Denver and going over mountain passes will happen. With my rig not being a diesel, I want to make sure I am safe. Wife wants a hard top; been looking at the Lance 8-9 series campers. Any advice is much appreciated.

Not new to this, in the past I had a Ford F-250 6.0L but got rid of it due to it being a lemon. I got sick of it breaking down. It worked well when it wasn’t in the shop but decided to get a nice size truck with a gas motor.

Thanks,
Mike

  • Your rear axle rating will be the maximum on your tires at full rated pressure. Check your tires, and see what they are rated for first.

    Campers have different centers of gravity, and a shorter camper will sometimes have a center of gravity ahead of the rear axle. This transfers some of the weight forward onto the front wheels. In your case, your wheelbase is 140 inches, so if you can find a camper with a center of gravity 14 inches ahead of the rear axle, 10% of that weight goes on the front wheels.

    But the real problem is the boat. A 4000 pound boat would have a tongue weight to deal with. If we say 15% and lets just say that the pin is 1/3 of the wheelbase behind the real axle, then 4/3 of 600 pounds goes on the back axle, and 1/3 of that 600 pounds comes off the front. So the actual effect on the back axle is now 800 pounds from the boat. Even if your tongue weight is 400 pounds (the minimum for a 4000 pound boat) then you still add 533 pounds to the rear axle.
