Second the recommendations
Like Stefrobrts, we have the BAL leveler as well as the BAL compression chock. The leveler works great and is sure easier than trying to get JUST the right amount of chocks under the wheels for side to side leveling. I did find that the tires on our '02 Bambi were too large to allow the leveler to slide easily underneath, especially on rockie sites. I fixed that by slightly expanding the leveler by standing on one arm and pulling up on the other. Probably didn't change the distance between the arms more than 3/4" but now the leveler slids in perfectly. The BAL compression chock is a unit that also slides underneath both sides of the tire, but it has a long jackscrew that you tighten against the wheel.
Also the McKesh mirrors work great. I can easily see the cars closer than the required 200ft (ie anything 200' behind the trailer must be visable in the mirrors). I also added a convex mirror on the McKesh mounted on the drivers side. Between the McKesh, the convex and the normal outside mirrors, I have NO blindspots on the either side of the rig.
