My vote, first vote, goes to the Rubbermaid Cool Seat, black hard plastic. Plastic hinges didn't last long, so used nylon rope. But for long drives in hot humid weather, it was the best cool seat to keep your backside ventilated and cool. All those wire and plastic ones were too compressible and barely lasted one driving vacation. I still have one. Only one. Use it every day as a limo, truck, bus, school bus driver.
Second one I invented; an air brake button leash, unless you are that stupid to let the button hurt your hand every time you pull on the dash air brake button. Never seen a short rope one in a truck stop. Sure does save your gloved or especially ungloved hand.
Third, a 1951 Chevy "suburban", tho that model was called somehing else , way back then. Passenger jumpseat folded under dash.
Lots of leg room.
Could hose off interior after hauling yard trimmings to dump.
Had very reliable straight 6 cylinder engine.
Big stick shift "H" pattern on the floor, where it belongs.
4 bench seats with wingnuts to remove from durable and easy to clean rubber floor.
Our family had a 1941 model and a 1951 model, as Dad bought a new car every 10 years and did his own maintenance on brakes and engine.
The "black mariah" and the "green bean", great family vehicles for a family of 6 and all their backpacks or suitcases, and I mean all.
We loved those 2 cars.
Can't get them anymore.
