Daryl,
A few years back I had the OEM airbag on the drivers side blow out at speed. My oversized tires immediately began grinding away at my wheel wells, but control of the coach was never an issue. Fortunately a safe pulloff place was across and just down the highway. I got on the phone to jim K. and had the quadra bag system sent to one of my intended destinations. At the time, I made the choice to avoid a repeat of the bag blowout scenario, though I repeat, control wasn’t an issue.
It took me two days to install the quadra bag system with my dexterity roughly equivalent to a lobster. Straightforward, good instructions, with only one change with a hand grinder to avoid contact with an oddly placed brake line.
Now, many miles down the road, I am more than satisfied with the system. It handles well, gives me good leveling travel and is one of the few “systems” on my project coach that doesn’t keep me awake at nite.
As Dolph has so eloquently stated: “Your mileage may vary, Batteries not
included.” To which I would add… “...some assembly required."
