Quick Advice on WY mountain driving

I'm about to go down a grade over here in Wyoming, bet some of you guys are familiar with it, the one where lincoln monument is, you know the one where it looks like Abe got beheaded or torso cut in half. Any ways ive gone down the grade before but today there is another factor involved there is a constant breeze goin on about 40+ and gust up 60, should i take my time and ease it down and let the wind jerk me back and fourth or, go down with some speed and keep pulling the trailer and try to push through the gust. If any one has any helpful tips they'd be much appreciated

 

Yea they are cross winds, as far my weight 41,000,

 

Should I even worry about it. Since I'm heavy, its just that 60mph gust cought me lastbnight it shifted the trailer to the next lane I tryed to speed out of it but she wasn't picking up any speed . I managed to slow way down then down shifted out of it, I would of thought being heavy I wouldnt have to worrie about wind, proved me wrong
