I too would be interested in hearing youroo's method. Seems like it could be a good one once you get a system down.
Unless you're using one of those BAL Light Trailer levelers (single axle only), then I don't think you will any noticeable difference with 2 axles. You'll just need more or longer blocks of your choice for placing under tires.
I currently use 5'x8" pieces of rubber stall mat...indestructible! I also mounted a Hoppy level to the pin box, viewable through the rear view mirror. Sometimes just moving a tad can eliminate the need for levelers altogether.
