Hight winds

Hello all, this is our first trip in our Thor four winds , we had a wedding to go to in Wyoming so we left Oregon went through Idaho, Wyoming, Montana. Now we’re heading towards Seattle… The winds are terrible. We’ve never driven this before and the winds are so bad… Plus in our last RV spot we went to empty our black tank and the handle broke off so we’re heading into Pasco to get it fixed… I guess I’m asking a question how do people go through these winds like this? Should our windows on the passenger and driver side be up or down? I know it sounds like a crazy question but we’ve never been in motorhome before, probably a crazy trip to take for the first time..
