I had similar experience back in my snowmobile days. I rode a 1975 Yamaha 433 GPX. Notorious gas guzzler. I carried 2 one gallon gas cans with me just in case. Ironically I never once used the gas in my sled but bailed out several friends many times. My sled at least had a sight tube to give you an idea on the fuel level. most had no gas gauge, no speedo or odometer, peer in the fill hole with a flashlight or rock the sled to see the gas sloshing. I estimated that sled got about 6 miles per gallon but it was sure fun. Drifting before we knew what drifting was. The engine was a free air so the colder it was the better it ran. Anything below zero was wonderful.Simple...I did drive my Viper and road tripped it out there with the NorCal Viper club. I think we had at least 15 cars in our caravan. The fuel wasn't specifically for me, it was just in case some of our other Viper brothers ran short. Some of the cars were older and I don't trust old fuel gauges or human judgment as people can have brain farts. As you know, there isn't a gas station on every corner when going from Reno to Winnemucca and then from Winnemucca to Salt Lake City. Having an extra five gallons meant the caravan wasn't stuck on the side of the road waiting for AAA or some road service to show up should someone have miscalculated their fuel usage. I don't leave anything to chance when I have to rely on others.
