Apparently they are the rave. I'm not as familiar with their uses in jeeps, however I know the 7.3 diesel guys like to run both batteries on the passenger side of the truck and open the driver side up for air tanks/more air flow to air box and other goodies. They last a long time, no corrosion, and have a good warranty. Another good point is you can mount them upside down along the frame rails or something and they'll still work! You can submerge them, drop them, basically take a hammer to them haha although I would not recommend that!
