OK, I realize this thread hasn't been posted to in "a while," and there may be no future posts, but when I ran across this I felt a need to add my 2cents.
The tile looks very nice and is a great warming addition to the PC. Good for you! Always fun to upgrade for further enjoyment.
As far as the airbag conversation, I do not have them on my 2011 3100, bucause there really isn't a need, in my circumstance. All loaded up with toad or other trailer attached ready for a road trip, the PC is level and looks good. Where my experience with air bags comes in is with our previous camping machine. We had a Ford F350 dually crew cab diresel with a 10.5' Lance Camper in the bed. It was a heavy camper, even had a generator, and it was challanging for the dually. I added air bags and it helped the side sway and leveled (it only needed a little bit) up the rig. When I did the install, I put in independant air lines, in case I needed more air in one side than the other to keep it level side-to-side.
Since the dually is/was a 6x6, I had to add the air once the camper was loaded, and release the air before the camper was unloaded, b'cause the additional height of the truck reached the limit of the electric jacks. Ahhh yes, past experiences. The PC is so much easier - just climb in and go. Again; just my 2 cents.
