First, I feel terrible for Eric’s mom. Must be awful.
Second, get poor Clementine towed home or to a parcel of land and rent her out as an Air BB type deal. I get the idea they have come to the same conclusion, but still. Rigs under the best of circumstances are not designed for full time living. It actually voids some factory warranties let alone a C class built in 1976!
Third, if they try a new set up just buy something new or nearly new and decorate it. i Suspect they are going to go with a truck camper of their own design. Oh boy.
