Air Bag Pressure

So i just finished up installing my Firestone ride rites with the day star cradles.
Everything went well, although i realized ill need longer bolts as my leaf pack is too thick for the length of bolts they supply. I had to flip the lower bracket plate in order to make them reach. Ill grab new ones tomorrow so hopefully it'll be ok.

Anyways, i carry around 500lbs on a regular basis with my tools, misc and canopy.
I got it sitting back to level with around 20psi. Rides pretty good, not too stiff.

Im finding it odd though as my drivers side is inflated to 20psi on the button, and the passenger side is at almost 27psi, and the passenger side is still a good 1/4 lower than the drivers side.
I would have thought the opposite considering the fuel tank is on the drivers side, and with the notorious taco lean.
My load in the back it pretty evenly distributed as well.

Not a big deal i would think, but i found this kind of strange and the opposite of what i was expecting.

A few pics for fun.

 

Also, i have a half tank of gas which could be a factor.
Im obviously being anal here, and this shouldnt matter much, i just found interesting.

 

Nice truck! Can you post up a few pictures of the finished install? Very interested in adding this mod to the books

 

I am running around 25 psi with my setup. Canopy and shelving in the back so it has a bit a weight in the back.

 

Can you tell me a bit about your setup?

 

Theres a lot of threads on here with pics and install instructions. I dont tow much, but there great for the added weight i consistenly carry. And when the time comes to pull my trailer every now and than im glad to have them.
