When I was considering purchasing a Roadsmith, one of the features that I liked was the ability to have additional fuel on board for long stretches without fuel stops. Now according to my Brother-in-law who has traveled out west multiple times, he claims you don't need extra fuel, just stop at every station without passing any up. Well I guess that depends on which roadway you are traveling on. So while doing my usual do diligence in research for auxiliary alternatives I have discovered this product. It appears to be just the ticket to take with you when you venture out on those long distance trips, without having to have it contribute to excessive weight when not. I plan to contact the manufacturer next week just to verify my safety concerns and about mounting it in my trunk (vapor issues). I will post an update after my further investigation. It comes in multiple capacities.
