Parking the truck in San Francisco

Been there done that many times. Depends on where you go in San Francisco. There are parking garages at Pier 39 but get there early, like around 8-8:30 am. Other places have parking associated with the facility like the Bay Model, Ft. Mason, etc. Other options are to use the ferry system from Sausalito, or if you opt to come in from the East Bay just ride BART. Concord/Martinez BART station has always had plenty of parking even for crew cab duallys. One other option would be to camp in the Delta and drive to the first BART station, typically Pittsburg/Bay Point. Rio Viento is an incredibly nice RV park in the Delta and about a half hour drive to the BART station.
