Indeed. And unless you have hella stiff springs in the front, I wonder why you went that high in the rear. Stan Martin's full race truck runs about 650 lb rears.
For stock coils up front, and assuming that I'd still like to drive it around town, I would be starting at about 300 lbs in the rear. Anything more than that (at least with leaf rates) begins to make the rear end jumpy and the ride harsh.
Any any rate (no pun intended), the coilover design makes spring rate experimentation simple task.
And for load, a set of helper airbags will allow you to carry anything that the engine call pull.
