I like it, especially for an overlanding/camping trailer. I found a bed locally for $2000 and have been toying with the idea of scrapping my trailer build and going with the gladiator bed idea.
303 has been used forever on airplane dashes and interior trim. It doesn't seem to off gas like armorall. If it is good enough for $35k-several million dollar planes, it's good enough for my jeep.
I did some night driving and the stock halogen lights are absolutely worthless on the trail. I really like the look of the full width KC hilites if you are running this setup, how do you like it? Is there a noticeable amount of extra wind noise?
My battery in the cherokee died and left me stranded. The dealer told me to go any auto store and buy a decent battery, otherwise I would be back in a couple years getting another over priced battery replaced. Gotta like their honesty!
