I am investing in my 99 TJ for a long cross country drive (I know .. it's crazy). In researching carrying extra fuel, I came across the Titan Trail Trekker II Tank. This is a solution that is creative and seems ideal and less risk to theft or vandalism. Anyone here have this? Thoughts? My one concern is the additional 100 lbs of weight on the read door hinges. Suggestions on upgrading the hinges to Heavy Duty. Is it needed? If so, which brand and model number? Thanks as always to this community for taking time to read and offer suggestions. Much appreciated!
