I would run out of range several times a year and think i'd only ever have to do that once to learn never to try again. I make a couple 16 to 18 hours at a stretch drives. No way would I tolerate breaking that up into extra days or being stuck in some remote town twiddling my thumbs for hours and not being a third of the way there yet.
On last summer's trip i'd have been really up the creek if I was in an electric car and was still plenty concerned driving a gas one after a shortcut in northern California ended with a blocked road 100 miles in... and had to backtrack the same way that extra hundred then find a gas station which involved trying several towns and running down to less than 3 miles of range left. The egg under the gas pedal driving style is perfected when you have 34 miles of gas left and the next closest place to get it is 35 miles away.

After getting gas I still had to detour to a road that meant an extra 200 miles of driving to get to where I was going 20 miles from the blockade.

As it was the long detour meant driving triple digit speeds to get there.

My brother used to have a propane powered Dodge van. Not a conversion a Canadian factory built one. He tried to drive to Mexico, he had a list of all the propane stations the whole way. Since there was not enough range on I5 south of Stockton he had to take 99. He had no problems getting propane until then, the next station was open 9 to 5... he gets there after 4pm and it is just a tool rental shop and the pump was in the back through a 3 foot wide door. He had to take the tank out which took him all of Friday night into the next morning. Laying in the dirt using minimal hand tools and the bumper jack to get enough space to get the tank under the rocker panel.
Then the guy who fills propane wasn't there Saturday, they weren't open Sunday so it was Monday morning when he got it filled and Monday late afternoon when he had the tank back in the van and turned around for home.
