Hi guys. Following up with my experience over the weekend. The X-chocks and two added stabilizers in the middle helped IMMENSELY. I was able to get a good night's sleep despite an 11 and 12 year old being on the other side of the trailer.
By the way, these scissor jack two-packs are a great deal: http://www.amazon.com/Eaz-Lift-48830-Leveling-Scissor-Jack/dp/B00IKKS4W8 I was not expecting good quality for the price, but they are very nice and smooth and all surfaces zinc coated or powder-coated for rust protection.
I am considering replacing all four BAL legs with these jacks.
