They sure are nice. As nice as many regular homes! That Little Guy reminds me of the Dewdrop ones from back in the day.
I can see pros and cons to each of course. Maybe a 5th if you already owned a nice diesel pickup. However then I would miss being able to walk in the back and grab a drink or something. Maybe a nice diesel in a medium size. You know big is nice, but also harder to drive and maneuver. Of course mo re fuel and a sizable price tag to start. It is something I could see taking months and months of really taking notes and comparing to get it right. But hey, I always enjoyed the shopping aspect of the deal. Great post as always!
