Thank you all for the information. I ordered the roadmaster from etrailer the end of Feb. Received a phone call from etrailer telling me it will be the end of May first of June before the roadmaster will ship. Apparently they are back ordered. I have been patiently waiting. I will however cancel if I receive another phone call delaying the shipment and go with Safety T Plus. I am also looking at the Sumo Springs. Hopefully with in the next couple weeks it will all come together.
