I read this forum nearly daily. I haven't posted lately and never did post frequently, but it does seem a shame that the activity level here is less than in the past.
As for why we like our class B, it's pretty well been covered already, but we like the fact we can drive and park almost anywhere easily. We get relatively good gas mileage, can pull in a campground, plug in (or not), relax, sleep and unplug and go again in the morning with great ease. We have everything we need in a small and easy to care for package. For road trips, spending only a day or two per stop, you just can't beat the convenience. For longer stays we still find a B quite suitable, as we tend to take day trips from the campground most days to explore the area.
As you can see, we love our B. Would love to join in a B rally when I retire. As a farmer, we just can't get away in May.
