Thanks,
Yes, most everyone was surprised at how well the truck did.
If I pull again I will make some blocks to go between the axle and frame to limit the rear suspension droop. Apparently the sled pulled the rear down around 6", and I have some really really stiff springs!
I will also need to fabricate a stronger hitch, as the current one has no direct path for the load to go forward, it is not triangulated. It is sturdy, and plenty strong for a normal trailer, but it did bend the hitch back about 1/4" in the center.
I would also give consideration to some more aggressive tires.
I really enjoyed pulling, and given a chance I am pretty sure I will do it again.
What I really want to do is sell the Ford before I am tempted to hook to another sled and chance braking something.
Then finish my Chevy with the Detroit, and pull it, as I will be 100% sure of the strength and quality of the parts and my work. While the Ford seems to be nicely built, and plenty strong I just don't know it completely inside and out yet.
