That's all I got for ya lol, sorry I couldn't help more. There are 5gal Jerry Can (the metal ones) holders that you can bolt anywhere, I've seen peple mount them on their roof in a yakima loadwarrior. I just got a 5gal plastic gas can and bungied it to my giant tupperware box in my cargo area that held a lot of tools/misc stuff.

I have seen the cardboard foldable gas cans but don't think they're a permanent solution, just a "crap i ran out of gas but oh look i have this cardboard gas can that the gas stations sell".

eta: And yes, that first link wont fit your X because its meant for the 1st gens. But its an idea if you end up getting a rear tire carrier, you could have someone fab it up for you to hide the cans there.

eta: That last one looks pretty good, don't know much about it though.
