Anyone have an idea what wind speed will turn over a travel trailer? OR, actual observations?
My calc's indicate 72-73 MPH wind in perfect conditions (nothing upwind of the trailer, wind exactly 90 degrees to trailer side, 70F, sitting still, etc).
I'd say your estimate is pretty close. Last May a couple of us were towing our trailers south on I15 just north of Salt Lake City on our way to Moab during a big wind event (winds at 45+, gusting to 80). The freeway was closed to high profile vehicles, so we had to jump off and find an alternate route. The only alternate route was on the east side of the freeway, towards the mountains east of Salt Lake, and the wind was also coming from the east, meaning we were heading into the worst of it.
Driving east into the wind wasn't a big deal, but once we turned south, the wind was exactly 90 degrees to us. That was a very white-knuckled 25 mile drive before we got out of the high wind area. Even driving 20 mph, the wind kept pushing me a full lane over. My buddy in front of me had a small Lance 1575 and a gust hit him so bad that it moved him over a lane and a half and almost lifted the street side tire off the ground. If it wasn't for the slide and fridge on that side, I swear it would have gone all the way over.
All the big rigs were parked and taking refuge along any building or retaining wall they could find and there wasn't even many passenger cars out willing to brave it. We passed a police car who probably thought we were insane, but he never pulled us over, since the road we were on wasn't technically closed to high profile vehicles.
We were on a tight timeline, but it was dumb to keep pushing on and we were lucky. I won't drive in winds like that ever again.
