I know that it costs more than traveling in a car, but I do like having my own shower, toilet, and eating facilities. I also do not have to pack things into and out of a motel room and hope that it is clean.
My DW can move about freely when she needs to stretch and then return to her seat. We still stop about every hour or so so I can stretch. When we had the TC we were stopping quite often. The ride in the MH is a lot smoother than the TC. If I get tired along the way I can always take a short nap in some parking lot somewhere and then continue on.
I do get to meet to meet and talk with a lot of great people in this land of ours with the MH, where in a motel you never talk with anyone. I have come across less than a handful of people who were not friendly at all. JMO
