Does anyone know why running boards are not an option on hybrid models ? I'm the main source of transportation for my 79 year old Mother, and she will be unable to step up into the MMH without them. Plus, I like the look with them on that I've seen on regular models. Since I'm not itching to carry around a step for her to get in, does anyone know if there's a physical reason for this omission ? Can they be dealer installed ? Any aftermarket models, etc... DD
