RotopaX Pack Mount Extension 5 5 2 2
Great Product I use this to connect my 2 gallon Rotopax + 1 Gallon Rotopax together. At first, I was thinking, $23+ for a simple screw and holder?! When I got it, I saw how complex and well designed it was. I do wish it would include some more in depth instructions. Like what to do and what NOT to do. Be careful when spinning this in, because if you don't pay attention, the block (while spinning) may puncture your plastic tank a little. I had a buddy talking to me while I was doing it, so my attention was half assed, LOL. SO tell your buddy to wait a moment :-p May 27, 2014
High quality; does the trick I use this mount in conjunction with the standard base mount to mount 1.75-gal water and 1.75-gal fuel to the Altrider rack on the back of my G650GS. This is a great combination and I couldn't be happier with it. January 22, 2014

Lee M: There are 2-gallon packs. In fact, I think the original size they offered was the 2 gallon. They're slightly thinner than the 1.75 gal. You can see that Revzilla offers both - http://www.revzilla.com/motorcycle/rotopax-gasoline-pack

Rotopax's site was down when I posted my question, but now that it's back up, I see I need part # RX-EXT. The part # for the 1.75 gal. pack is # RX-1.75EXT.

Peter W: There aren't 2 gallon Rotopax containers. The 1.75 gallon size is probably what you're looking for. I have two 1.75 gallon containers and that works perfectly for me. Jun 17, 2014
