Yeah, I carry an MSR type bottle with me but the largest you can get is 33oz so not much. With the tank mod I'm looking at getting another gallon and that should do me very well. Just need to find an old tank. I don't have the tools to do any metal shaping not that I would to do much but cutting the piece out of another tank would be real easy.Ray, you don't carry a flask with you? Maybe a camelback will do the trick! Great idea, I've run out twice in 3 months!!! Thinking about storing extra fuel in the frame!!! Hmmmmm!
