Which route to take, rear set up.

Hey guys, so I dont know which route to take, maybe someone here can help persuade me.

got a 2017 DCLB, - in the rear i got a camper shell, bed slide 1000x.
- right now i got medium dakars and 5100.
- with all this weight im starting to sag, developing this bro lean.

-every time we go camping, the back is loaded with the rtt, for sure the back is sagging hard.

So here are my options:
1. heavier leafs
2. air bags with same medium leafs. (already own a single ARB compressor), would just need to purchase the bags and system.


- i would like to know which one would be an over smoother, and smarter route.

Thanks in advance.

 

Air bags

 

Heavier duty leafs. Airbag is more of a bandaid
