Achieving level tow with Ram 3500

I had a similar problem with my fiver after trading my F150 SB for an F350 SB with 14" longer bed. The fiver had a Reese Sidewinder pin box that couldn't be raised without locking out the Sidewinder function. After a rear axle bearing failed (4 or 5" nose high), I locked out the Sidewinder and raised it 2" which helped. No problems turning with longer bed but a rough ride. I had previously swapped from MorRyde CRE3000 equalizers to EZ Flex which lowered the fiver, so I stopped at MorRyde (called ahead for appointment), installed CRE3000 equalizers to raise it and the MorRyde pin box which was higher than the Sidewinder. The fiver is now level and rides good.
As I said in another post, I am now replacing the sloppy Reese 16K hitch with an Andersen Ultimate for the lighter weight and to eliminate the clank when I start and stop.
