Wheel House springs

[opsirc]

My son and I are thinking of building a wheel house out of an old 5th wheel trailer frame. It currently has two axles under it, I was going to take them out and replace with a single heavier one that would swivel up and down. Would use the front legs and add two 3000lb trailer jacks welded to the back to raise and lower. Trouble is I can only seem to find springs for the wheel with a 9/16 eyehole. I am worried that this will not be big enough to hold the weight when towing. The house would be approximately 18ft long and 6 1/2 wide. Are there springs with bigger eyes on them out there or will these hold. most of the weight should still be on the truck when towing.

Our ice castles have a 9/16 pins on the springs

Even a 7000# trailer spring still only has a 9/16" bolt in it. Shouldn't be a problem.

maybe its just me, but I have been looking at both houses and photos of the spring system on houses. to me it looks like there is no way the spring can move the way they are attached.

On most frams the spring is drawn down between a U shaped flat iron strap, a hole is drilled in the strap thru the -U- about 1 1/2 in from the bottom, A pin is inserted in the hole after the spring hits bottom,The bolt or pin lays across the top of the spring. The hole in the end of the spring isn;t used.
