If I am on a hard surface, I use nothing under the stabilizer pads and nothing other than the jack foot under the tongue jack. If I am on grass/dirt/sand/gravel, I will put 1 Lynx Leveler square under each of the stabilizers and under the jack foot to distribute the weight more to keep it from sinking and having to do it all over again. As far as leveling side to side I either stack up the Lynx Levelers or planks of 2 x boards under the wheels on the low side until level. Usually you can eyeball it and see if you need 2 boards or 3 boards.

I use Legos as required for levelling side to side and sometimes front to back but I always maintain a non insulated earth connection on at least one of the contact points. So even at an overnight boon dock spot, like Walmart, I will put the jack down. Jim
We use the Orange Lego Blocks for side-to-side leveling of the Airstream. Under the tongue jack we use a piece of treated 2x12 with a metal "tongue twister" that allows side-to-side movement of the hitch for hooking-up.
We like the Legos much better than lumber for leveling. The Legos are much lighter and versatile. On tandem axle trailers, the Legos can easily be made into a ramp to change a tire.We have done this on the road anumber of times. We used our Legos just a couple of days ago to mount our new 16" wheels and tires.
We carry three sets of the orange Legos. They weigh about as much as one or two pieces of treated lumber.We also carry four Lego caps or half height pieces.
How high did you have to go with the Lego blocks before the other tire came off the ground to change it?
I have a tong twister I use on the front jack. I have 2 2X4 cut a little longer than the tong twister and use them as needed. If I need more then 2, out come the lego blocks. I recently purchased the Andersen levelers for side to side and am extremely pleased with them. I used to carry 3 sets of legos, but now down to 2 sets. Like others have said, on ground I use at least one lego to spread the load. If a hard surface typically not unless it his a long stretch for the stabilizers. Cordless drill speeds up the stabilizer process.
I finally got tired of replacing cracked chunks of 2X dimensional lumber. A trip to the lumber yard for a 12 FT micro lam (engineered laminated lumber), cut into 1 FT lengths has eliminated all splitting. A combination of lumber and legos satisfies all my leveling issues.
