Glad to hear you make it ok.
Rental gear is scary. I rented a trailer when I went to pick up the Cambridge, Uhaul.
Got it the night before, took it home. All 4 tires were at about half the specified pressure. So I checked the lugnut, several were not torqued to spec.
No issues during the 12+ hour round trip but I am glad I decided to check the tires and give it a once over. But it does make me wonder what other people are pulling behind them.
Yeah, I went through the trailer and tires before making the haul.
When I rented a trailer to pick up the tug it made it 6 miles loaded before a dent in the fender ate the sidewall of a tire. While eating up the spare tire, I limped it to a quick lube shop to have the tug serviced and then eased it home. When I returned the trailer I gave them a good fussing about the situation.
When I rented the second one the girl at the store said she made sure I got the new trailer so I wouldn't have any problems.
