I am pulling right now and before the IS install when I would go on/off bridges or bumps some of the movement would transfer into the truck even through the trail air. Now the truck does feel a little movement from e trailer but very minimal. The recovery when going on/off bridges is very quick.
I have the Firestone bags on my truck running right now @ 60psi.

So far, we use the "earthquake putty" available at Camping world and probably other locations. It might also go by the names of:
Stay Putty
Rock & Roll Gel/Putty
Quake Putty
Quake Hold
Museum Putty
Mystic Clay
We purchased ours at United RV in Fort Worth:

So far, so good. It does not leave a stain and everything has stayed in place. Even through the Oklahoma and Illinois HORRIBLE roads.
But still, if there is any extra cushion to be had, I would at least look into it.
Thanks for posting.
