We have driven numerous times from Boston MA to Missoula MT in our pickup truck in all seasons and really enjoy the trip. We have towed all sorts of boats and trailers. Except for Chicago it really is a mellow trip. My question is how will our new motorhome (Class C Travel Lite 25 ft handle through the mountain passes (we are new to driving this type of vehicle). There are a few long 6% grades in Montana and Highway 93 into Salmon Id is steep and windy. We always see large motorhomes towing vehicles in these areas and they make it look like a breeze -so any tips other than commonsense safe driving would be appreciated. thanx in advance
