Cross winds

if it felt tippy, the cross winds were too strong to risk. Stay put!

I've been driving my dually with 6000lb camper in winds that would blow the boot I had between the 2, yet never felt any danger.
So it is definitely setup -unique and dually certainly has huge advantage.
I also have RWD, who is 3" lower than 4WD and that plays role as well.
Semi trailer are not only 12' tall all the way, but also sit higher, so COG of empty trailer is pretty high.

Good to know so I can be more aware in the future. I was glad to have added the swaybar before we left.

I'd imagine some of the tip potential is getting pushed off course and the sharply correcting exacerbating the roll forces.

A Google search yielded the information that 30 to 40 mph winds will push trucks off course; possibly into the next lane. 60 mph winds will tip a truck over. I'm thinking that trucks are more stable than Truck Campers and I would start looking for an exit if the wind got to 30 mph CROSSWIND. Headwinds or tailwinds would not be as big a problem.
Just my $.03

Agree! When winds hit 30mph I start looking for a rest stop or any safe place to pull over and wait for the wind to lower. "you have everthing to gain and nothing to loose by pulling over"

This from KSL, Salt Lake, this morning. T-storms in the area yesterday.

“...TOOELE — Roadway wind restrictions on I-80 in Tooele County were lifted Thursday a few hours after being enacted, officials confirmed.

However, a wind advisory remained in place after at least one semitruck blew over on I-80 about 11 miles West of Knolls, according to the Utah Highway Patrol.

At one point wind gusts up to 70 mph were reported along the freeway. Winds were reaching 45 mph as of 7:50 p.m....”

“... Initially, semitrucks, RVs and other large vehicles were prohibited from driving on I-80 between Wendover and Tooele but the restriction was lifted just before 8 p.m., Utah Department of Transportation officials said.

In its place, a wind advisory was issued for those large vehicles until 9 p.m. Drivers in the area should expect residual traffic delays, UDOT officials noted.

Additionally, parts of the county — including Knolls, Clive and Low — were placed under a severe thunderstorm warning until 6:45 p.m., the National Weather Service Salt Lake City reported...”

I wouldn’t drive in 50 to 60 MPH winds.
