Not quite as facile as having an ability to climb stairs, but this gets another job done. Hauling 200 pound loads over a large sand dune and saving the family, and me especially, a lot of work. The Teensy 3.2 in the control unit does a wonderful job of managing the interface and commands and radio data stream. Thanks for all the support and good ideas.
