Maybe this will help in leveling your TT. Buy a set of RV levels with the graduated scales Hopkins Graduated Level #08525 ( about $8,00 a pair) Each degree equals one inch either side of 0 (zero) .The Hopkins brand has both an adhesive strip and screw holes/and screws included. Attach the levels to the drivers side of the TT on the front corner and the side corner using the trim molding of the diamond plate in the front of the TT as an example for a reference point for level. The Yellow plastic or Links Levelers are one inch rise for each block, just add the number of degrees off center and stack the blocks as needed. Over three blocks high requires a stair step stack or the trailer tires will just skid on the asphalt. The State Park we usually camp at is from two to three inches out of level side to side and sometimes five or six inches front to back. One has to be "creative" in getting the front to back level.....front down near the ground means the back is way up in the air, (our entry door is at the rear) requiring a folding step and wood blocks for the rear stabilizers. Everyone has his or her ways to get the thing level and there is no right or wrong way, just be safe and CHOCK those tires before you unhook from the tow vehicle. Happy camping to you!
