To the O/P.. I will tell you a story.. The Lollypop cop (Public Relations officer) was speaking at my High School.. He explained how much he knows about cars
He knew where the gasoline went in
And where the money came out of.
(I suspect he knew quite a bit more but that was what he said)
He mentioned his wife also knew where the oil went in so she knew more than he.
MANY people are really that clueless when it comes to cars, trucks and RV's. Me,,,, Well I have done a major overhaul, I've replaced clutches, dropped and replaced Transmissions, U-Joints, brakes (pads, Shoes, Rotors and Drums) and more.
If you are not afraid to tackle a repair,,, Odds of being stranded are small.
IF a tire that is 20 PSI low on air is beyond your ability to inflate.. or worse yet, CHECK... odds increase a thousand fold..
