Cool Rear end sag

Hello All, my 37G seems to have a sag in her rear, I don't feels she is loaded very heavy. I'm considering putting air bags on the rear hoping this will remedy the sag. She already has new Koni's FSD front and read. Any other solutions come to mind.

Shocks will not have any impact on sagging. Air bags to provide more arch to springs will likely make the ride firmer. I don't know your coach but I would look at replacing the springs to address the sagging issue. But, first, get it weighed so you KNOW it's not due to overload.

There is a lot of weight on the extended rear end and the fulcrum effect adds to the problem. I took mine to a spring shop had the springs rearcked and added an extra leaf. On another rig I had 3Ts add air shocks which cured the problem.

my 50G has a bit of a sag in her rear but I wouldn't like to suggest any changes because the couch is very uncomfortable

I hate guessing on stuff like this too, agree step 1 should be weigh it. If you look at the GAWR and find you have capacity available, take it to a spring shop and let them give you an opinion re-arc vs. added leafs?

Well, da**, my rear is sagging too, but that comes with my age I guess!!

Now, the MH is a different story as we have air suspension so if the ride height is set correctly it'll never sag.
