I suggest sitting out the wind if you can. Coming across Iowa last month there was a stiff crosswind. Our rig handles it very well since the truck weighs almost as much as the fiver and we don't have the side wind resistance of a semi.
Still it was enough to keep me alert and about 5 mph below 62 where I usually run. During the day we saw three semis blown off the road VERY recently and one RV - could not tell if it was a fiver or a TT since it was a pile of kindling stacked on top of the pickup! Very scary and depressing. The trailer was in the median, a semi was on it's side off the right shoulder. No way to tell what happened, but the odds are it was wind effecting one of them
