To pnichols,
Wow, thank you so much for you thorough post above, especially for the benefits of the E450 chassis! You clearly thought through the offroadability details very well! This will help us think through it too.
Have there been any situations where you wish you would have had 4x4, or have things worked smoothly with your design considerations?
We go off-highway in our Class C usually because of our hobby (rockhounding). And yes, there are many opportunities to go where only an ATV or small jeep should go - that we have to pass up. But we can also travel to many off-highway places and camp right there close enough to walk from camp.
We do not want the hassle of towing something, even though our Class C could easily do so. However, I have thought of carrying a true offroad motorcycle - such as the superb two wheel drive Rokon offroad motorcycle - off the front bumper for real exploring where allowed. A long time ago we traveled and camped in a 3/4 ton Dodge van that we bought new and converted into a camper. We carried a Honda Scrambler on the back of it for getting way out there. Myself, the DW, and our dog rode on the motorcycle all at the same time when exploring ... using the van camper as a home base.
We avoid situations with the Class C where we anticipate that our 2WD traction may not be enough, and we so far have managed to stay out of traction trouble. However we do carry along a shovel, an extended lift jack, and several wooden blocks and boards to help us get unstuck if ever needed. 4WD in our Class C would only be for insurance purposes in extreme traction-loss situations (i.e. getting caught off-highway in wet conditions). With it we would probably still not go any further back into the booddocks than we already do. That being said, I can imagine highly unexpected situations in which 4WD in our Class C could turn out to be priceless. We probably would never need low range even if we had 4WD because of the E450's already great low rear differential ratio of 4:56.
But be reminded of what I mentioned earlier in my post: We have no problem traveling below 10 MPH for miles on rough roads when and as necessary in our Class C - which for many folks would be intolerable. We're retired, patient, and the Ford cab (with coach bathroom access for the passenger when moving slowly) is comfortable enough to permit a snail's pace when required!
