Newbie fed up with so much misinformation on set up of a TT

I REALLY want to try the Anderson Levels. So far I just can't get over the price. Lots of good posts... To add my two cents, I run both low side tires on blocks and run the stabilizer jacks down snug. Occasionally when one Jack is put down too far the entry door will stick, so trailer frames certainly can flex. I also use X-Chocks on both sides, which dramatically reduces front to back rocking.
