I guess I am still in the "gee whiz, what will they think of next" phase -- I very clearly remember a world not only without the Internet and cell phones but without personal computers, and without answering machines (really!). So the pace of change is still interesting to me, and I am looking forward to the time when RVs in general begin to feature advanced technology at reasonable prices -- carbon fiber, high capacity batteries, ultra rugged components, etc.
So, why not legs, too, as long as I'm dreaming?? ;)
