There are many vehicles on the road with rear gas tanks besides the KJ, WJ, XJ and other older jeeps. My KJ has a gas tank skid and a class 3 hitch. I am not worried about it.
Years ago I had a Bronco11 with a rear mounted gas tank, a gas tank skid and a class 111 hitch. (similar set up to the KJ) I was stopped in traffic and got rear ended by a camry and he went under my bumper and hit me dead center on my hitch and drove it through his radiator and into his hood and folded the hood. You could still see the squaire imprint of the hitch in his folded up hood. (LOL) ....They had to tow him away. I had no damage to the bumper or hitch or gas tank skid or gas tank.
Anyway, every vehicle rolling down the interstate at high speeds is a rolling fire hazard if the circumstances of the crash are exactly right. I am not worried about it.
