4x4 Class C, what do you think?

We have a 2005 24ft class c that we had converted to 4wd last year at Advanced Four Wheel Drive in Salt Lake City. Like Gary's it has manual locking front hubs and a manual 2 speed transfer case and a solid front axle. The conversion requires a 4 inch lift, and we also went with 235/85/16 tires which gave us an additional 1 inch of ground clearance. The extra ground clearance from the lift and larger tires is probably at least as useful as the 4x4 on rougher Forest Service roads. We have used the four wheel drive mainly in the winter driving in snow up to Tahoe for ski trips. Our conversion cost about $12000, but money well spent from our point of view. And it actually seems to handle the winds on 395 pretty well.
