Motorhome/toad make trip down Teton Pass

I remember reading in a truck or RV publication many years ago that the Teton pass among some others in other locations is not recommend if not actually prohibited from use by motorhomes and towed trailers. Before I started my trek thru the Rockies, Cascades and Sierra Nevadas with my TT I did my homework research well and avoided those suicide spots. Some people are too smuck lazy to do this though. Cheers to youa.
