Need for pads/blocks with hydrolic levelers?

You shouldn't need them for additional lift. If you need that much first try to reposition the coach.

What many will use pads for is to make a bigger foot print and spread the weight of the coach out. You want to avoid leaving makes in hard surfaces of an improved campsite or have to climb under the coach to assist a jack that has sunk into the ground and won't retract.

Simplest, lowest cost jack pad is to head on down to your local big box store and pick out a fairly straight 2" x 12" x 8' plank and have them cut it into 12" lengths. The wood might split with use but being dry makes for great kindling if you slit it some more. The more purpose made pads you can buy can cost anywhere from a few dollars to over $25 each.

Long term low cost landing pads are 2" x 6" lumber sandwiched between 1/4" or so plywood. Even if the 2 x 6 splits the ply holds everything together. Saw one owner who actually urethane sealed the pads.

Well Sir,
Not all campsites/RV spots are level. And some, are quite unlevel. "Repositioning" isn't gonna cut it if the entire site is unlevel. And, many folks say, "Well, if it's that unlevel, just move to another spot". Yeah sure you're going to do that, when every single campsite in the park is spoken for and, you've had reservations for months. We've camped all over the U.S. and, without a doubt, bringing along my small lumber yard which includes ramps, blocks, and more, has come very, very useful multiple times when the sites are less than desirable.

You are right about "sandwiching" the 2x material though. I did it with twin 4"x6"x 11" blocks. I put 1/2" plywood on both sides. They're indestructible. I've also got ramps made from 1 1/8" in decking plywood. Those too are indestructible. Yep, they weight a little bit to haul around but, when you're driving on something with a heavy diesel rig, you want them to last.
