So I measured how much the rear sags when I load the camper onto the truck. Measured at the centerline of the rea axle, it drops 4.5 inches. Is that something airbags or Sumo Springs can fix? Or is that a level that would require a more drastic mod?

TIA

Air bags can definitely raise the rear 4.5 inches. Keep in mind most trucks have a rake (high in rear), so you might not want to go all of the way back to 4.5 inches.

Sumo springs, Timbrens, or Supersprings could also work.

I don't know if I would be concerned with a few inches of sag. It takes a couple just to even engage the overloads on our truck and if you have those you definitely want them in play. Otherwise airing up bags to lift off the overloads just trades one set of springs for another (which are usually further inboard as well).

If the headlights are an issue turn the adjusters a bit.

Our camper is getting loaded in the coming week. I'll take a measurement of sag if I remember but I'm fairly sure it's at least 4 inches as well. With a our truck it takes it from rear high to close to level.

Side to side momentum is a function of all the weight big campers carry up high. Fridges, air conditioners, storage, stuff in the storage, storage, more stuff, more stuff on the roof....

Pickup rear suspensions sag as a function of using long taper leaf springs to give some kind of ride empty.

Handling suffers because as sag occurs the steering castor angle rolls back toward 0.

Anything you can do to hold the truck at or near stock ride height when loaded will keep it handling and braking like it should.

Then start fine tuning for rock and roll control. Getting the truck to steer normally first will help a lot.

You just want to LEVEL the truck, not bring it back to unloaded ride height.

Since you refuse to acknowledge or try my suggestions, then all I can say is that any number of suspension aids will help.

After reading the varying comments and suggestions, I ordered 2 products from Hellwig. One is their Big Wig sway bar. The other is their 3500lb helper spring kit.

I will be having a local garage do the install, but it might not be for a few weeks. When I get it back and test it out, I'll post the result. Maybe I'll need to get new shocks too.

BTW, my tires are E rated but I did not check into their weight rating. And they are inflated to 80lb on the rear and 60lb on the front.

Thank you all for you info and suggestions.

As a side note, something happened the other day that was interesting to keep in mind. I had the truck in for service which included tire rotation. They rotated the tires, but did not change the pressure, so I ended up with 80lb in the front and 60lb in the rear. The TPMS caught it right away and I got it fixed the next day.

Sounds like you have a plan. How much did your rig weigh and are you well within the tire/wheel load capacity and GVWR?

The truck is rated for a 4400# payload. Considering I removed a 100# tailgate that gives me a 4500# payload. The camper is supposed to be about 3400# with a full fresh water tank. So I'm guessing, fully loaded we're close to the limit, maybe a little over when the gray and black tanks are full.

Isn't that just the water from the FW tank?
