    I just got back from a camping trip. Had about 500 pounds in the cab and about 400 in the bed. The back of the truck seemed to sink more than I expected from such a small load. I felt like I bottomed out a few times on the trip on the highway as well. Its an 05 V6 pre-runner double cab. I may need new rear shocks, but I didnt expect the truck to sink this much and it felt loaded when driving. Any ideas on how to fix? I guess adjustable shocks for load vs no-load? Anyone experience this as well? I expect it to go down some, but what If I were towing as well. That would have killed me I think.

    500 pounds total in the cab (people plus cargo), or 500 pounds of cargo in the cab?

    I loaded my truck up with wood and all my camping gear. I dont know the weight drove 6 hours south to Valdez through the mountains. It ran like a champ, only downfall was i had to downshift my 4 cyl on some of the steep grades but gas was good.

    if you don't qualify for the TSB to be done on Toyota's dime, spend $100 and get an AAL. It'll take you and a buddy about an hour and a hlaf to do both sides. Well worth it.
    I recently did this myself.

    Add-a-leaf. That is the fix to your problems.
    I have used the AAL that comes from Toytec.com. You can't go wrong.

    The AAL works good at fixing the sagging problem. However if you are hauling a lot of weight they springs still don't hold up too well. Another option (whether you have the TSB or not) is the Timbrens. They retain your factory ride, but when you start loading up gear, or haul a trailer, they prevent your truck from sagging too much, yet still allow the suspension to cycle properly.

    So, AAL and Timbrens are my two options. I see the Timbrens only have 1" of travel before they are engaged. I wouldn't think this would be enough to keep the original ride of the truck(unless they engage with minimal resistance and slowly). Looks like Timbrens are around $200 and AAL is around $100. What to do...

    Leaf spring helper at local autozone for 25 bucks is the best bang for the buck IMHO for what most guys need.

    Pretty sad Toyota didnt think of actually loading the truck before selling it and finishing the design. I mean really.

    thanks for all the feedback.

    As said before, get the Rear Spring TSB or and AAL. I got the rear spring TSB done a couple months ago and it made all the difference in the world. Now I have a functional truck.

    I got some Hellwig helper springs (1000lb rating) and it helped a lot (~$120). I had a camper shell installed and I noticed the rear suspension sitting further down. Drove it for a while hauling bikes and gear. I eventually decided to invest in the helper springs. Worked great for me. Feels like I got my travel back when it's loaded.

    My $.02.

    Foglights are for fog, not oncoming traffic!
    Airbags are another option.
    Replace bump stops with airbags and control how much pressure with air fittings.
