since my trailer has grown in weight to about 1700+ lbs, I had to use a wood/metal contraption I had hobbled together in order to put the trailer back in the garage (photo of the contraption earlier in album); I finally got around to using a modified 2"x 18" long receiver extension to fit into the frame rail, after I removed the factory tow-hook-it's bolted into the same holes, using grade 8 hardware- just for slow movement into the garage bay
