...O.k., I'll blather first.
The IMS 3 gal is simple easy and just enough gas for your every weekend 150 mile jaunt. Doesn't add alot of weight, i.e., handling isn't affected.
(Just Gastanks gives a discount too!)
All the big dog adventurers here think they need great grand gallons of gas to be complete. Well, gallons add weight
So think about what you really need.
If you're planning for that trip across the Gobi, best go big.
If not, go small, save cash, and carry one or two petrol bottles just in case.
The Safari is a looker though...
See the tool tube? Perfect fit for a gas bottle!
