In the top picture you can see the stainless steel handle going across the near end of the gas can.(it's not as close as it looks, but the 2 gal won't fit between) The bike is a standard GS, but I put on the GSA rear rack which has those handles. The regular GS don't have them so the wider 2 gallon size will fit fine. It could also be shimmed up an inch to go over those handles on the GSA rack.
Rotopax is expensive (for a gas can) and I've left it in the sun on 100+ degree days with no leakage. I've ridden several thousands of miles in 7 western states in all kinds of weather and never had a problem.
Edit; There is a similar gas can called Kolpin. I have no experience with it, but I've heard complaints that they sometimes leak, and aren't as well made. I've never heard of a leaky Rotopax, but obviously, it's possible.
