Rear tow/air bags affect on shock/spring performance?

that is a super sexy sled deck, i wanna build one. do you have a build thread for that? would you say the bp 51's still ride great unloaded with the airbags at minimum 5psi? was curious on this exact setup the bp 51 with airbags as i tow a trailer and have dirtbikes in the bed.

 

I installed Firestone air bags in the rear bnb of my 2012 Tacoma 4x4. I regularly put up to 2200 lbs in the bed. They work great ! No longer am I bottoming out , and the ride , at 30 psi or so, is great ! I installed them myself, the first side in 3 hours , the second side in 20 minutes!

 

I have been using Firestone airbags for about a year now. I have a topper and pull a 5x8 enclosed trailer with it making a round trip from Minnesota to Washington State a couple of times. Those bags make all the difference in the world. https://drive.google.com/file/d/1Q2EIHfcvpF0k3ReYZjpSGU1f8hIsf4GR/view?usp=sharing
