Skid Wheels for low camper

I could not back into my driveway with my 5er without dragging on the cement. It was so bad that I had problems pushing the drag skids up hill and it really dug into my drive. I took it to a local welding shop and had them weld a 2" square piece between the frame ends and then weld some solid steel, non swiveling wheels to that. They cut off the skids that were on the trailer so that the wheels actually were a little higher that what we started with. I am very satisfied with what I had done and would do it again. The solid steel wheels are so solid that there is little chance of them hitting and being peeled of or bent over.
