Welcome to the forums Jim!

MH subfloors are typically 5/8" particle board. The floor joists are typically 2x6's. The best way to get rid of the uneven floor joint would be to relevel the MH. Basically you would use a bottle jack to raise or lower the MH frame where it sets on the block piers. Inserting or removing shims will change the height. You woud need to either lower the frame at the affected area or raise it near the outside edges.
