Airbags installation for heavy 5th wheel
I made a video of my airbags installation on the truck a few weeks ago. My 5th wheel tows much more confidently, less bouncy with the extra support. For any interested: https://www.youtube.com/watc...

To everyone saying 80 PSI, this is not the case. The tire sidewall says:
LOAD RANGE E MAX LOAD 1700 kg (3750 PSI) AT 450 KPA (65 PSI) COLD.
The tire is Toyo RT 37X12.50R20LT 126Q 10 P.R.
Note that it is a 10 ply, not a 12 ply. Regardless, we can't say "E rated means 80 psi" anymore.
Bounce, Bounce, Bounce!!! The "D" tires are NOT good for hauling a 5er. Carrying capacity, YES but sidewall stability NO!
Sounds like you made a stop at LesSchwab!
I think you misread the above. Note the tire sidewall. They are E tires, not D. I don't notice any bounce with the tires at 65 psi and the airbags at 85 psi. The bouncing was happening BEFORE I put the airbags on and is nearly non-existent WITH the airbags. I drove over some good highway rollers a few times on the last outing and was grateful for them.
