Advise on raising the rear end of a CF350 Motorhome. About 3.5T

[Stevo]

Its not that I mind the power steering effect of a heavy motorhome body on the back of the CF-350.
But I'd like to even up the heavy assed profile a bit. I was thinking of fabricating longer rear spring hangers or airbags on top of the rear springs. But surely that would just raise the front the same height because the weight distribution is still the same?
All ideas appreciated. Looks like it needs a 3"  lift. How would one go about this?

Get your leaf springs reset to the desired height, any decent spring place should be able to do it.
