ive swapped alot of 3/4 ton suspension stuff on my C10. the 1 ton stuff is heavy duty for sure, but what are you planning on towing?

I believe you could weld in crossmembers and stiffen the frame. Add beefy springs with some air ride. I would bet that you could pull a gooseneck without any issues as long as your drivetrain was up to the task. and it would be a great build thread to read, Just Sayin!
