Our MH front is always lower than the back. This means the front always has to come up often with the wheels off the ground to level it – worse with uneven RV sites. We carry boards that we put under the wheels. We do this by going a little higher than we need, put the boards under, let jacks back down then raise again. Right now the site we are on is so bad we have 3 boards (about 6 inches) under the front tires. When we set up a spot at my sister’s for us, we sunk the boards for the pad about 4 inches in the back because of the way our MH is built.
