Snow, driving with slide out...

We're in Las Cruces, NM, spending the holidays with family (staying in an RV "resort"). It started snowing a little after noon yesterday and we've received 4 - 6" in the Mesilla Valley as of 11:00 this morning. Late last night, a large class A DP pulled in across from us, apparently getting off of I-10 in the bad weather. This morning we've watched him spend a couple of hours trying to clear the snow off the slide toppers. He pulled his tow'd - a full-size pickup - around to one side to stand in the bed to try to clear the slide topper on the street side. Not being able to clear the heavy, wet snow off the topper (which was sagging to the point of laying on the top of the slide), he just hitched up the pickup and pulled out with the street side slide a little more than half way out... my wife watched the slide wobble as they pulled out of the park. I hope whatever he's in such a hurry to get to is that important!
