One more thing about carrying extra fuel, the CARB fuel cans made it difficult to add fuel from them. I had a long funnel that fit through the restricted filler neck hole . . . in the garage back home. We jury-rigged a funnel with a water bottle and hose that we use to add water to the trailer. I now have a proper funnel in the trailer and both vehicles.

(The firefighters below are adding extra fuel to the Tahoe. One is pumping and the other is holding the flip-up door open with a pen. I could have offered them my makeshift funnel but they were having so much fun.
