Question 2 - Should wind affect a good set up truck

On a recent Alberta trip we were following others going camping down the highway, it was windy and EVERYONE was swaying. If the wind makes you sway the only two things you can do is go slower or wait it out at a rest stop. There were 20 of us in a wagon train with all kinds of set ups and each of us thought the same thing as we pulled over then proceeded on a secondary highway at a slower pace.
