Hooking up ramps to the side of the trailer

I just rested them on the rub rail. It was fine. Biggest pain was getting the cart how I wanted it I had to go back and forth a ton of times. Finally got it tho.

 

Can you just kinda chain them to the rub rail or just under the rail and use some dunnage to make a ramp from the trail to the ramps? Depending what the cart is I'm sure it can be done. 400lbs you said? Find 4 strong dudes

 

I had one last year in Durant,OK. He came out six miles to me. I do need to catch up with the times.

 

Knowledge of what's available.
We had rollbacks in the forklift business, small independent. I picked up some nice coin doing things like that and on Saturdays moving the little backyard sheds for people moving nearby, as the moving company preferred to pay me from his HHG take. They removed contents, I moved the shell... Most shops/guys owned, would be glad to pick up <100 for a change of pace...
