We drove our new to us at the time 2001 Tradewinds 37' DP from Maine to Albany, NY in a snowstorm.....she handled great!! slow driving, no abrupt changes of speed or direction, plenty of following distance... maintain momentum up hills....
I assume you are coming up 81 then west on 17/86....IF it is snowing, the "hills" on 81 thru PA might be an issue... 17 should probably be well plowed.....
The big question is: where are you going to stay?? Is your MH 4 season?? How about your plumbing system??
