I have a hightop Nissan NV, and with the solar panels and roof vent cover, I'm about 10 feet tall. When the van was new and lightweight, before the conversion, driving in high crosswinds, even at 55mph, was a white-knuckle affair. Things improved greatly after adding 2000 pounds to the van. I have a travel trailer now (also around 10 ft tall) and even with a weight distribution hitch and sway control, wind can make things interesting.
I've been in New Mexico since February and the winds are brutal here. It's not unusual to have winds in the 30mph range or higher, day after day.. I'm doing the New Mexico State Park shuffle, so I must move every 14 days. The prevailing wind is crosswise to I-25, my main route. I make things much less difficult by moving the trailer early in the day, before the wind kicks up. If I keep the speed below 62mph and the crosswinds are less than 20mph, it's not too stressful.
The ace up my sleeve is that, since I'm retired, if the weather is too awful, I can just call ahead to the next park and let them know I'll be coming in late due to the weather. Many boating/flying/recreational activity accidents are due to people HAVING to go out in dangerous conditions because of time constraints. If you can be flexible with your traveling times, you will be able to reduce the dangers of inclement weather greatly. And an even better tactic for extended rotten weather is to just pick up and head to greener, calmer pastures.
A plus in being above to deal with travel delays is to be able to dry camp, to not need hookups. As long as I don't want to run the a/c, I can boondock indefinitely, eliminating another time constraint
