Thanks Linn. It definitely gives some peace of mind knowing that everything is strong enough for the job, and theoretically shouldn't give any problems down the road. I'm also comparing what Ive built to the stock frame as part of the project. I'll post up the comparison and my other calcs once I get them all typed up(Not looking forward to typing them all). Here's a few numbers for ya, based on A500 2x3x.25" steel tubing and the overall weight of the truck plus 1000 lbs. The numbers are based on just one frame rail, and do not take into account any crossmembers or additional bracing.
Max shear stress=389psi
Max bending stress=2700psi
Max deformation(located in middle of the frame)=.0877"
