I called JT today to better understand the Elephant Foot pads and the lady who answered the phone wasn't that familiar with them. She's going to have a guy call me back next week whenever he gets back in town. She stated that JT merely distributes this item for Lippert and that they have very little info on it.
I also called my RV dealer (RV Wholesalers) and they weren't that familiar with the JT Elephant Foot pads either. The tech there stated that they rarely sell them. These things have been out for at least three years, probably longer...hmmmm.
I like the swivel that the previous poster displayed
