@jerry 's recent post about Adventures In Xmas Tree Delivery with a U-Haul truck reminded me I've never told this story here. So, my own U-Haul experience...
We were moving my partner from another city to mine, about a two-and-a-half-hour drive. Rented a U-Haul truck, whatever was the largest they had at the time. 17-foot rings a bell, but I'm not positive about that.
It was built on a Chrysler/Dodge frame, and had a 10-cylinder diesel engine. It still felt under-powered.
I was the one to drive it to Saskatoon. Loud, uncomfortable ride, but uneventful. But as I approached the outskirts of the city, something just felt a little "off". Nothing I could put my finger on. Until I reached an overpass that goes over train tracks, so a little up-and-down hump in the middle of flat prairie.
And as soon as I hit that hump, *something* went wrong with the engine. It coughed loudly, was immediately down on power and running roughly, and in the few seconds it took for me to check my mirrors and see what options I had, it started belching white smoke from the exhaust. That's coolant in the cylinders, meaning (at best) it blew a head gasket, and (at worst) put a connecting rod through the block. Probably not a big enough bang for that.
Couldn't even coast it up the rest of the hill, so it was stranded on a narrow overpass, almost touching the guardrail.
