Setting up travel trailer on grass question

[Captain Skippy]

Granddaughter is purchasing her first camper, most likely a 28 ft rear kitchen Keystone. Setting it up on our land which if fairly level, hard Carolina clay type soil with grass. What should I put under her electric jack pads? Thought about concrete patio squares that are about 18”square but they may break. Wood will absorb water and rot. This will be temporary for several months. Concerned about rain softening things.
Thanks.

How about a layer of gravel for drainage and then some pressure treated lumber?
Or CAMCO plastic leveling blocks

Concrete patio blocks first and wood blocking on top of them. As they settle she will need to add some pressure. If the concrete does crack, still under 10 bucks going toward a good cause.

You will also want something between the tires and the ground / concrete, I use rubber patio pavers

All good advice. Thanks.

This is what I'd do.
