LOL, that's a funny thought... well, we flipped another one - the Pontiac this time! As for the hair out of place, I remember the stuff we used to use back then (a little dab'll do ya) and it would take more than a simple roll over to mess your hair up!
My guess is the trailer wasn't loaded properly, a long shallow slope and it started to fishtail. Inexperienced dad hit the brakes too hard when he should have hit the gas. Cal
