My Safari 3.7 works well and I think the lifting pump will pretty much drain it. I took 3.6 gallons at one stop last September.
Re: Rotopax -
How safe are they in a crash? I have entered the Alcan5000 for 2014 and the rallymaster won't allow them for safety reasons. I need 170 miles fuel range and I'd like to ride my 690R. Since 170 miles would be a stretch I was planning a Rotopax using the Wolfman rack mount. It puts the tank on the side of the bike. Anybody fall off with a Rotopax? Any issues?
I only really need a gallon. Rally Raid has a 1 gallon rear tank that would work but it is $600!
