So, I have a 2 door JK I'm planning a 10 day trip with. I have a rooftop tent mounted on Rugged Terrain rack. I'm wondering if anyone has suggestions on externally mounting a 20 pound propane tank? I don't mind drilling into my rack I just can't find a bottle holder that 1. I'm comfortable mounting to the rack and it NOT swinging or 2. not sure yet if I'll have enough room on the rooftop rack to mount one. Because I'm running a 2 door jeep, space is at a premium. Thanks in advance. If it can't be done reasonably, that's okay. I'll just use that as motivation to build a trailer.
