We are taking delivery of our 303 this coming Friday, July 11th and are scheduled to have the dealer install a B&W Companion same time. We are now second guessing whether we need a slider or not. Our road is very narrow so the turn into our drive is a little tight. We can bring a 40' goose neck in, but that does not come anywhere near the cab. The truck is a 2012 F250 crew cab 4WD short bed. Anyone with a similar set up have recommendations? Thanks.
