After 8500 miles, I’ve discovered that you can precisely cut a piece of wood, drill a hole to insert a key ring in one end and hang it on the tab inside the gas cap. And when you fill up with a gas nozzle that has the ratchet catch removed, you have a prop immediately available. So you don’t have to stand there holding the handle while filling.
This, after I discovered there wasn’t a gas cap to use for this purpose, like my ‘16 had.
