Dragging Back going up driveway

I have a 2011 Berkshire 390QS that drags the back when we go up the driveway of our new home.

Is there a way to over inflate the rear air bags to raise the back for this?

Has anyone put on Drag Wheels on this model? If so which ones and where? Do you have pictures?

How about curb bridges?

Looking for any suggestions.

You may try approaching your drive at an angle (assuming the dragging takes place at the approach end)

Figure where it is going to hit. Then lay a couple 2 X 6 boards behind tires. Probably 2 rise be enough to get past your scrape point.
