The steering stabilizer only stabilizes the front. What's the issue with the ride in your Jeep? If the ride is rough, lower the psi or add weight to the rear.
What is the issue with the ride? We drove our Max Tow Gladiator over 108k miles in 5 years, so that we had to replace my wife's car with a Bronco Sport to absorb the miles.
If you worry about the mark from the fuel cap, you might not want to drive the Jeep to the mall. The cap is plastic and won't leave a mark. The fuel cap on mine lays against the fender without touching the bed.
Gonna be hard to have a market if no one is buying them. I wouldn't want an easy way for water to enter my fuel tank.
