I would not use that on a TT as it is no different than the standard stabilizers that come on one by the look of them. The frame is not designed to be lifted from anyplace except on the suspension box area right above the axles to change a tire. I mean come on it only takes 10 min to setup a trailer anyway. Once you get on to doing it you get pretty good at judging how many boards you need to level the trailer and IMO for the all of 2 minutes it takes to drop the stabilizers well I can think of a dozen things that actually make life easier besides wasting money on toys like that. My wife and I can have our trailer level and hooked up to all the services in under 10 mins and she has a bad back, so unless you have disabilities save your money. or just order a new FR trailer with all electric jacks and stabilizers if you don't already have one. Another thing if you happen to break or bend up an electric one and need it replaced, there are alot of dealers who don't stock stuff like that, but you will always find the good old standard hand crank stuff pretty much at any RV place.
