It's going to weigh about 160 pounds when full. That weight will be multiplied whenever you hit a bump depending on how fast the truck rises. At the least you should put another thick (1/8" or larger) strap under the flange on the tank to spread that load and not have the force concentrated on the bolt heads or bolts with just washers. The straps are a REAL pain (they don't fit at all without mods) but they spread the load of the tank over a large surface area where the metal is thin.

Oh, and you have to trim the last crossbrace on a SWB. Probably on the LWB also.
