Hi David,
Our 2007 2350 built on a 2007 E350, has the rear end sag when loaded up for a trip, primarily from the 42 gallons of water sitting directly above the rear bumper. If you wouldn't mind elaborating, I'd like to know three influences from your Super Springs. Your information would help me in determining if the Super Springs are right for us.
1) How much height was gained at the rear bumper?
Our rig when empty, cannot tolerate much additional height for the a/c unit on the roof would not clear our garage door.
2) I assume the handling while driving was affected. Could you describe the differences?
3) I also assume the rear suspension was made stiffer? Do things inside the rig jolt around more since you added the Super Springs?
Again, I would appreciate your inputs in these areas.
Ron
