I have the 5lb, and its nice. The clamp it metal on metal with a slottel nut so if you overtighten it, it will go to hell in a hand basket fast. My girl help me pack back up and did this for me, thats how I know, power tank gave me a free replacement band, and I swapped the nut to a nylock nut I replace every few trips for like $0.05.
The mount is stupid expensive, but so is the clamps (also did fourtreks clamps) since mine was custom since I drive and Xterra and no one makes anything for an X I had to drill my own holes for the application. Used grade 8 SAE hardware, its not going anywhere. With the longer hose I had built at evco house of hose. I dont even remove the tank when camping anymore. Just plumb to it to the 22" Partner steel stove. I know I have a photo showing the tank and 4 cans, just cant find it right now. Sorry. But you get the idea.
I found I can use the 5lb tank and 4 2.5G (10L) runt cans on the lower portion of the X Gobi rack at the same time. (or 6 runt cans only) couple this with a second row of runt cans on the incline which fit like a glove with the Tepui Autana Ruggedized on, and 2 5gallon (20L) mil cans on the maxterra rear bumper, I have enough to do almost anything I would need ever include bugging out. I have 6 runt water cans, 6 runt fuel cans, and a dozen 20L fuel and water cans. I really like the runt cans as they just barely clear the rack where the 20L stick up big time up there. I use to keep a set a 4gallon rotopax up there, but I like the mil cans alot more for dozens of reasons. They are just harder to find. but cost about the same if not less that rotopax.
