Buddy - if your host position on the Parkway is actually on one of the Parkway Campgrounds look carefully at your route in. There are a number of tunnels and bridge underpasses that a Redwood will not fit through and turning around is not an option. Last time I looked there was no way I was going to get through a 12' underpass in one piece !
Have fun !!
