I tried to get MAF's 24 gallon tank last week, but someone else got it. They only had one left and Steve was checking to see if they were actually going to take it. After numerous calls checking back in, it appears that it did sell. Darn it!
But more will come in....someday.
In the meantime, I'm in the same boat. I don't think the stock tank will be enough, but I have no rear tire carrier or roof rack so niether option will work for me.
The only thing left is interior storage using fuel cans. Not the best plan, but it's what I do in a pinch. The best sealing fuel cans I've ever used are the Wedco nato cans. They are airtight, don't leak and I've never detected a single bit of vapor.
The next best thing about the Wedco nato cans is the different sizes. You can get them in 2.5 gallon and 1.25 gallon sizes. I have all three sizes, but now leave the 5 gallon ones home. The 2.5 gallon cans are small enough to be able to fit in different nooks and crannies and it's much easier to fill holding a 15lb can, than it is a large 30lb 5 gallon can.
The 1.25 gallon cans are neat, but considering my 80 burns that up in about 15 miles, they're kind of not worth the hassle. But if you need a really small, really sturdy can, that's an option.
One word of warning...you don't want to leave the gas cans in the vehicle in the heat of summer during extremely hot weather. I found a 2.5 gallon ballooned in the back of my CRX. I can only imagine the pressure that the can was under to cause that. But it is a testimate the can's strength and the fact that it will not vent anything into the interior..short of exploding...of course.
