Parking MH on dirt

I was at an RV park in Southport NC with a medium large diesel pusher, about 30,000 lbs with six tires. I used my washer/dryer several times a week. The ground is sand there. To keep from sinking in I used 4 foot long untreated 2X12's under each tire. I used 9" X 16" X 3" solid concrete blocks under the leveling jacks; after 4 months I had 5 deep of them buried under the softest two corners. The closest 2X12's had only sunk about 3/4". I re-leveled about weekly.
I have actually stayed there 4 times, at least 2 months at a shot with 9 months the longest. One time another Big RV stayed there for a couple weeks and needed a wrecker to pull them out after sinking in up to the rims.
I chose untreated lumber because; it was cheaper, I thought the chemicals might mess up the tires and I was abandoning the lumber. I normally use PT 2X12's about 2 feet long under the leveling jacks and 4' long untreated 2X12's under the tires in many situations. I jack each corner up with a 12 ton bottle jack to put the boards under the tires. If you stay awhile it can be a better idea than sinking in. Normally I do try to stay where I can park on asphalt or concrete, or worst case gravel. I travel and stay to work. Sometimes the only thing you can find is mud or sand.
If you have a smaller, lighter rig; then adjust accordingly. When I had a 27 foot travel trailer, I used 2 foot 2X6 lumber. The stationary occupied weight was about 8000 lbs on 4 tires and 4 scissors jacks for stabilization and leveling. And of course no washer dryer.

There's dirt and then there's other dirt. It does not always behave the same. Sometimes if you think that way; you wind up in up to the axles. All it takes is a really good soaker rain or too much sand.

This seems to depend on location, why you need it, is your MH 2 or 4 wheel drive, have your levellers not taken the weight off the ground under tyres , tyre condition, inflation, etc.

Maybe a one size fits and and get track treads (or whatever you guys USA side call them), they can be driven over and left on site, help reduce sinking if its gets wetter boggy and can be used for snow and ice.

Once mans thought, but your circumstances might help as to why you're asking.

I bet that only happened to him one time.

Funny how hindsight learning experiences turn into foresight evaluation experiences.

I buy a case of king size "My Pillows" each year ... actually some good conversation.
