Soft Ground

I'm fortunate I can park my camper on asphalt at home. But I do occasionally park it on the grass. When I do, I always put boards under the TT tires, 8 footers. The tires will not sink into the ground, and this will enable the trailer to start rolling with a bit of momentum before hitting the grass. Once moving, it keeps moving.

To get your camper moved now, you may just have to wait till the ground gets good and hard and dry. You can do a number of things to get more traction on your tow vehicle. Does your truck have 4x4? If so, engage 4x4 and it will probably pull right out. If not, you may just have to wait, or call a tow truck with a good wench.

Any suggestions to stay on top of the yard?

Horse stall mats!

Yup, inexpensive, thick, won't rot, won't crack, wont' move when you try to roll up on them. Put a couple of them together and you have an inexpensive complete landing pad for the RV. I used it for the MH and no sinking and keeps the moisture away from axles/brakes, etc.

Pick them up at any Tractor Supply Store they are on sale in store all the time. They are even cheaper if you have a farm supply store near you.

Smooth finish or diamond plate raised.
Utility Rubber Mat, Black, 4 ft. x 3 ft.
Rubber Mat, Black, 4 ft. x 6 ft. x 3/4 in.>> 2 of these and you have an 8x12 RV pad.

Couple sheets of plywood or 2x10's.

Wait for the ground to dry out or refreeze
