Trucks have to have four doors and seat 4 riders. Full size vans are not allowed, and neither are 2-doors. Some knothead on here bragged about getting a 2-door past Uber. Then he questioned the matter of just how he might have been deactivated. He also had no TNC and was deliberately picking up in the CoH.
I once saw a 3500 once picking up outside of my local neighborhood walmart grocery store. (i.e. likely a $2 ride) The funny thing is, the trucks get paid the same as uberX. I have no clue why one would think its profitable. I just hope they are only testing the waters with the vehicle they have already to make sure it is something they want to do before getting another vehicle.
I used to use our F-150 (4-d00r) before I got a sedan. Definitely not profitable in the long run because of the MPGs.
Never had an issue though...most pax didn't mind either. Although they didn't want their luggage in the bed if I was taking them to the airport. I did feel kinda bad when I had to pick up this little old lady and help her climb in because it was a little too high.
