One of the reasons we wanted to go RVing was to get on some of the dirt back roads in the areas we visit. I've been a motorcycle rider all of my adult life and just sold my 'last' one(Heritage Springer)and bought a Wrangler. We do not do any 'rock crushing', but we've been on some roads, that unless you're riding an on-off dirt bike, a 'scooter would not have cut the mustard...not to mention the possibility of flat tires. We've have two 'flats' in some pretty isolated locations...would have hated to push a bike outta that scenario.
The Old Fall River Rd (RMNP), Road to the Sun (Glacier NP), Island in the Sky and the road to Gemini Bridges (Canyonlands NP) and many, many other roads we would have missed out on due to rain, temperatures, terrain or the lack of stability a two wheeled vehicle has when dealing with the road conditions (think cliffs/drop-offs of hundreds of feet here). Nothing like the solid feel of a Jeep under you.
We put over 12K miles of great back roads under the Jeep on our 10k mile adventure last summer...NO way could have we done that on a two wheeler!
With the two front panels off the roof and the 'blue' of big sky country pouring in, that'll turn back the hands of 'time' for ya!
Ride a TOAD!
