To the OP. I have a little bit heavier trailer than you with dual axles and also have a set of BAL Levelers left over from my pop up days. I have tried to use them and it was difficult to lift the tires so I do not recommend them for anything except pop ups or really light trailers. How ever, they do work really well for getting rid of the wiggle in the trailer after it is set up. Just slide it under and crank it up just enough to put some pressure on the tire. I use it every time I set up. Give it a try. I use the simplest and cheapest levelers with much success, 3/4 inch plywood cut about 18 inches long. Good luck
