AllenTC2: Either option sounds good to me. I also do the WV roadtrip and on many 1 1/2 lane gravels roads (you know what that means!) and have a 28' with Quigley 4x4. Been going back home to the farm for 14 years and crossed many creeks and pastures and have only ONCE put it in 4x4 to get up a creek bank. I have gone up to Snowshoe Mountain skiing and had 10" of snow to deal with and then 4x4 was required. As for rolling/flexing, just hasn't been an issue since I'm not trying to go where I take my 4wheelers. Just feels much more confident that the 4x4 option is there. Lastly, I installed it for my beach fishing trips and not for WV....but, it works on land and sea! Good luck.
