No shocks alone will not raise the rear end.
You need to either replace the leaf springs or add a leaf.
I just added one leaf and that raised the rear end substantially.
Go to a frame shop they have all the modern computer equipment to analysis just what has to be done to raise the rear end and by how much.
Remember leaf springs are metal and metal fatigues. How old is the MH?
We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.
