There's probably something to the 'tradition' comment.
The first stabilizers I saw had open aluminum frames. I think you can still buy them.
If you didn't put something under them, they would sink into the ground unless it was very hard and very dry. The first trailer I owned came with a set of home-made jacks that had for a base a kind of upside down, shallow bowl that was about 6 inches across. Real stable.
Then, we used to jack up the tongue 2 or 3 turns above level, place the front jacks loosely in position, then drop the tongue down to set them. Now, I have the dire warning that the stabilizers are only stabilizers, do not, repeat, do not, use them as support for the trailer. They have 6 inch square feet on them.
Of course, I put an 18 inch piece of 2X6 under each.

Beside putting the weight over a larger area, the wooden blocks allow some slippage for the foot pads without binding the landing gear so much.
I've made blocks out of 2X6s faced with 1/4" plywood to prevent cracking. We carry four blocks for the front and back. Also have two piece of 1/2" plywood cut the same size as the blocks to even out the landing gear if one side is uneven in height.

Pressure = force / area
Force should be relatively constant in your trailer (unless you air drop into yr campsite  ).
Blocks under the contact points of the scissor jacks increase the area that the weight (force) is exerted on.
Larger denominator (area) and a relatively constant numerator (force) = a smaller applied pressure.
Smaller pressure = less penetration into the ground and more stability/dispersion for small load changes (walking around trailer).
Think of it like snowshoes for your TT

Lots better. And the monkeys like it too. You can have a banana.

I am new to RV'ing but I did recently discover that using blocks and limiting the extension of my electric jacks greatly improved the stability of my 2011 Rockwood SUL 8313.
I was beginning to have real heartburn over the amount of movement we were getting. Keeping the stab jacks higher really helped. Plus i feel like blocks limit the scuffing of the stab jack paint and subsequent rusting. just a thought.

Actually people use wood on their stabilizers so that people know that they aren't witches.....
It's because wood floats ....since wood floats and ducks float, then if it weighs less than a duck, then she must be ...... a witch, and it would be very inhumane to use ducks for the same purpose.
So if you see a camper on wood blocks, you can be sure there no witches inside.
..if you actually understand that, you are complete loser like me & spend way too much time watching really old & bad movies

@Acara, I see monkeys coming after you. With heavy wood clubs. Or maybe ducks. It's hard to tell the difference.

stayed at a RV Park in Gattlinburg that require blocks under you landing jacks to protect the asphalt. If you don't have any they loan you some.

No bananas for you. Stand ready to be dashed with cold water.
