This is just the reason my wife and I went to a small MH from the TCer. She broke her ankle very badly a few years back and she lost some sense of balance and it bothered her getting into the camper. We had a nice NL 10 2 CDSE with a 2013 Ram dually 4X4 and decided to go back to a MH. I tow a Subaru Cross Trek to go out explore the back roads but have a nice unit to come home to. We are only 25'long and have twin beds in the back so we have the 3 steps to get into the unit and then that is all the steps we have.
We are both into our late 60s so this is the route we took.
