I've made the levelling job just about as easy as it can be without going to an expensive auto-levelling system. I use 3 tools to accomplish this:
1) a BAL leveller, which just happens to have a 3/4" male hex head
2) an 18V cordless impact driver with a 3/4" socket attached
3) the bubble level available at this link:
http://www.amazon.com/Hopkins-05515-...45682&sr=1-145 - it mounts on the trailer side and swivels 90 degrees horizontally so that you can check level both front-to-back and side-to-side.
Steps:
1) Chock trailer wheels
2) Remove WDH and sway bars, then remove trailer from hitch
3) Remove hitch bar from receiver
4) Check front-back level with level gauge, use electric tongue jack to achieve front-back level
5) Swivel level gauge and check side-side level - decide which side BAL leveler needs to go on
6) Install BAL leveler on tire that must be raised - use impact wrench to adjust to level
7) Chock the tire without BAL (optional)
8) Using impact wrench, lower scissors levelling jacks and engage to a few turns past touching ground/asphalt/blocks - they just happen to be 3/4" hex head, too!
The whole process takes less than 10 minutes and results in a level, stable trailer without much effort.
One suggestion about the swivel level gauge above if you buy it - install it on the hook-up side of the trailer and not the entry side. Otherwise the wind will blow it to the open position while driving (school of hard knocks lesson!)
