Yes, but two questions:
1. Are you guaranteed that next gas station you are heading to has gas? Or their tank isn't low so they're limiting folks to 10 gallons?
2. Are you guaranteed that next gas station is open? Not all places are open 24/7, and depending on what time you're driving through, they might not be open then you might be stuck there for a while.
With my Jeep and trailer combo, I should be able to go about 240+ miles just on the Jeep's tank. Add the up-to 14 extra gallons I can carry (9 on the trailer, and 5 in the Jerry can on the back of the Jeep) that gives me about an extra 210 gallons (so 450+ mile range). I really don't like that feeling of wondering if I'm going to run out of gas before I can get refilled. On my last adventure up in NW Canada, the Jeep started running like crap in the middle of nowhere, throwing codes (glad I carry a code reader and tools), and sucking down gas like crazy. MPG went into the toilet.
(FYI - Codes were saying I was running lean - got to next town and spent just over $400 Canadian at a NAPA on two O2 sensors, MAP sensor, air filter, throttle body spray, and two bottles of Sea Foam for the next few fill-ups... seems to have fixed it).
