Yep, press "recirculation" if you're a wuss and need
My Chevy Tahoe cleans up nicely with an auto car wash (most allow a few passes) then, after un-loading the fuckton of gear, me and The Kid vigorously attack it with a high powered, plug in type leaf blower, inside and out! I am amazed at what blows out from the interior, some good finds actually, haha!
After that we use a stack of towels with all manner of cleaning agents and at the end of the day it looks like new.
I'd use the Gerlach car wash but my timing sucks. It's a goooood idea to wash the exterior asap, in my opinion, because a playa dusted car is a cop magnet, so it seems these days. Life is unfair, but it's even more unfair when you get a ticket for a minor infraction just because you're transpo is playa dusted, erg!
Eric nailed it. I've seen over a dozen vehicles under shade shelters, maybe more than a dozen at some camps.
Car covers proper, I've rarely if ever seen in use.
I'm the MAN in a truck, burner who is stuck, you're in luck! I'll whip out my BIG tow chain and not charge you, not even one lousy buck!
