For those considering one of these for their trailer. (Wasnt sure where to post this feel free to move.)
AT makes an aluminum one:
Both of these you guys posted are the same one I reviewed.5 LB bracket with free shipping
I would figure out a way to just make your own. Get yourself some 3" wide bar stock and bend to an L shape. The figure a strap to hold the bottle. One like in the video with a gun lock cable to secure it should work just fine. Like I said in the video knowing what I know now I would not buy one at the price listed.
Not everyone wants to or can make up some Rube Goldberg tank mount.I fine it interesting that many want to spend twice what the tank costs to hold it. Doesn't ring true.
Making one from a poiece of strap and using a clamp to hold it makes more sense, cost less in the long run.
