Beef up Rear suspension

I am looking for suggestikns on how to beat stiffen my rear suspension to help my 2006 Tundra TRD handle heavy load.
I just built a large wooden camper thats sitting in my truck bed for work that weighs about 800lbs maybe and my rear is sitting very low. I want to be able to load 1000 lbs more of supplies if needed.

Any suggestions?

 

Heres the camper on my truck before painting

The tub is 99" long and the roof is abouy 6'9" off the bed. Probably too big. I was trying to get as much space as possible.

I had a 2002 Ford Mini school bus 7.2 deisel that I used for work and some asshole stole it so I have to use my Tundra for work now unfortunately

 

Try Firestone Airbags. I have them on my 04 Tundra.

 

+1 on Firestone air bags. I put them on my 2001 last fall. I wish I had done it a long time ago.

 

Thanks. Do I need anything to go with it? Like an air compressor?

And do u know if I need to remove this heavy ass camper before installing ?

 

I put air bags and cradles on a couple of weeks ago. 2 hour job, biggest hassle was removing bump stops.

 

You can run an air compressor but I just use the supplied valve stem and add air as needed. You do not need to take off the camper, just jack up the rear and then put it on jack stands. You'll need take off the wheels.

 

Does anyone have any recomendations for helping the sway? This thing feels like it wants to tip over. I see several dif stabalizing bars online

 

Hellwig makes front and rear sway bars for these, but kinda pricy. I'm yet to hear anything bad about them though. Addco also makes smaller bars for less $, not quite as good but many say they're pretty good for the money.

 

I used Airlift brand air bags.

If you plumb them independently, they help a lot with sway too.

No compressor. Very easy install.

 

Is there any way you could lighten the load by removing some of the really heavy structure and replacing it with some Aluminum pieces...
Using Al to make the frame, then sheath that frame with the plywood.
If you fail to waterproof that plywood, it will suck up and swell like a sponge. Adding even more weight to deal with. I like your idea, the weight is a problem.
Your center of gravity has really shifted up causing that sway!
Good luck, let us know what your fix is!

 

I put the Ikon AAL on my 2.5 gen and I am very happy with them. They make them for your 2006 as well. They are relatively cheap, and no messing with filling airbags, and my truck rides great unloaded and loaded. They will add about 1.5 inches when unloaded so it may not be what you want if you are not already leveled in the front. I had my truck leveled, and when I added the AAL it brought it back to stock rake and it drives great. Something else to consider if you are not already set on the bags!

 

You’re way over payload and have a really high center of gravity with this setup. The definition of Sketch. I would rethink this setup and go with a trailer or smaller canopy contraption. After the accident is a bad time to reconsider.

 

Installing a $50 AAL doesn't increase your payload.

 

You want to add 1800lbs with a center of gravity about the height of the cab roof? I think you will be grossly overloaded and will tip the entire rig over the first time you hit a tight radius exit ramp above 15mph.

 

Buy a trailer for it instead of putting yourself and others at risk. I don't see how you'd ever be under GVWR with this setup plus the 1000lbs of supplies you mentioned. No matter what upgrades you do to the suspension, the GVWR on your door and what DOT recognizes will not change.

 

you possibly have built the center mass too high. That thing being so wide and heavy is not wise

 

I wasn't suggesting the AAL increased payload. Nothing can increase the payload of the truck except for making the vehicle lighter. The airbags and the AAL help the sag.

Maybe if you are committed to driving that around, you remove the truck bed completely. You would be saving the weight of the truck bed and could build the camper to have more interior room while being smaller and lower. I think the best idea, and what everyone is telling you is you need a truck with more payload to do what you are trying to do.

 

Anyone catch the size of the tv box in first pic? Dear lord man you got an 80 inch tv and your makin a DIY truck camper?

 

2nd gen guys, go wring your hands elsewhere. I like it, drive safe.
