Hard to say without seeing it.

20% grade seems pretty ****ing steep? Picture?

Just put a couple of more bricks under that side of your trailer, cowboy.

if you are getting water over the foundation wall your grade is way too high at the house. You want minimum 4 inches, preferably 6 or more between the soil and siding.

Regrade the backyard, install a french drain if needed.
