If your talking about the washes behind the Glamis store here are the pic's that I have.
PICTURES OF THE WASHES AND SURROUNDING AREA.

Some maps in there also.

I made that page for an event/chatter gathering we are having during the New Years holiday.

The road is a decent road and any motorhome can drive on it. I suggest when you get tto the wash you want to camp at you get out and walk around before driving in.

 

here is a picture from wash 10 during the christmas to new years week.

p.s. however it will be packed come new years, so wash 14+ would be ideal for groups with small kids.
