The piece I want to mount the jack to with the three pinch rings was originally a piece of steel I-beam we had left over at work. I cut off part of the "I" and turned it into a "T". I hope to bolt it onto the wing brackets for loading and unloading with 4 each 3/4" bolts and it wouldn't be attached to the camper at all. I can't image it will flex much into the camper or side to side as it is a very stout chunk of metal. My old tripod bolted to the same bracket also, but this adapts the corner jack to the wing style lift bracket. I started making the three new wing brackets today and hope to have them done next week. The old one in the picture has seen better days and I have plenty of steel to pull out of the scrap bin to work with. I had read exoskeleton article and was impressed but I hope to try something less aggressive. Thanks for the feedback.
