rear suspension question please

Truck is a 2003 prerunner, going to add a snugtop pro fiberglass work style shell with fiberglass doors on the sides and rear, as well as a rackit lumber rack that fits around the exterior of the shell. What will be needed to keep the truck from sacking out in the rear with this weight and a few hundred pounds of tools ? truck has the bilstein's set on the middle setting with factory coils, for the most part she sits level unloaded now. Can i get away with a add a leaf ?
Thanks in advance.

 

get the dakar pack or allpro standard. it may sit stink bug without weight. id lift the billies to the tallest setting

 

Do not want to move the bilsteins up, sticking with 265 tires, and do niot want that kind of preload on the factory coils.

 

get a dakar/allpro pack and remove a leaf? maybe stop being a vagina?

 

If you get the dakars, the full pack will lift it 3" and 1 1/2 to 2" with your cap and tools. Mine sags just over an inch with 350' tongue weight....

So if your not lifting the front, dakars with a leaf removed or an AAL will work for awhile...

There are other leafs with less lift but not a lot of info on this site...
