Geez already
I"ve been watching this thread with interest.
I cannot see the correlation between having a stage 3 and the bed spread issue. There is only one explanation that I can think of and that is that the trucks that this has happened to have made some ridiculous jumps to cause this. I see the pictures.
These trucks are baja proven yes, but they are not trophy trucks guys. These trucks can handle some jumping but it seems like the purpose for some of you is to see how high and hard you can get it. If you want to get that big air then build a 4 link rear and put some real shocks on it with 36 inch travel. And those trucks do not have truck beds. They have a fiberglass shell.
Let's get real here. These trucks were not built to be jumping in the air ALL the time. No truck built like these are indistructable and you will see this type of damage when we do what we do with them with out building for it.
The triangular brace from bed side to bed is your best solution. There are tons of ways to build them. The simple ones on that white truck above looks decent but they are not going to be that strong with just a couple of bolts holding them on. The whole rear bed section needs to be framed and triangulated with decent thinkness's of flatstock. It needs to be done before you decide to jump to the moon with your truck. To fix it permanent you need to bring the bed back in spec and frame the bed as mentioned above with at least 2" x1/4" flatstock both inside the bed and under the bed in order for it to say put.
The first place I have always spent money on all my off road vehicles trucks, buggys, motorcycles is the suspension. You can only go so fast with stock suspension and no matter how many pony's you got under that hood, your suspension is your limiting factor.
Just sayin.
