Damn! That would be a nice setup. I didn't realize back when i posted that it was a sale price on the fuel pax. I just cant justify the cost for these. At least not this year, maybe down the line.Sorry, I told you wrong. Just talked with this member of the Midwest Overlanders who said he was able to double stack his Fuelpax using a 3 gallon extension and a standard lock mount. Looks like you're in luck!

Really good to know that it would work though. I think that will be what i end up doing in the future.
