Rving and the rigs we have definitely can change over time. I have done tents to the current DP. Personal ailments, locations we camp, and simple wants all come into play. I am currently trying to find a TC as DW ailments have made travel temporarily uncomfortable and I still want to go. Once she is back up and going I think she will camp in the TC as she did with our other one and just sleep on the dinette. I can also guarantee that the addition of a TC won't justify the removal of the DP as many trips the comfort and room make it just that much more enjoyable.
