Hey guys just a little interesting info i found out about our Berkshire while at a park in San Antonio last summer i noticed a new pull in neighbor with a trailer (they had the 390 ) with matching paint so i went over to say hello and after the intros he ask me if i had the door keys to my coach well i reached into my pocket and hey i do so, i handed them to him and he walked to his door and observed him locking his door with his key and then unlocking it with my key. Uh What?
he then turned to me and said every Berkshire he has met he was able to unlock his door with their keys now this did not unlock the dead bolt just the other lock he is a full timer and they have been traveling for 4 plus years. so this may be the master key? maybe.
we didn't try the storage key to see if it worked
