We do it when we stop for more than a couple nights,and know the county you are in for weather warnings. Usually I find them just by looking at google maps to see what’s around us. When boondocking with no phone signal we try to find where the nearest one is before we get there. And try to be real careful we don’t get hurt that we need to go. Having to go for a health reason is anyone’s guess as when that will happen. Wife says no climbing ladders when boondocking.
Same as most pre 2000 Ford Dome lamps in light trucks and same as the Third Stop Lamp in my old 1999 F250. Current Automotive number is a 912 or brighter intensity 922.
