We rented an RV to take to Burning Man. We knew it was a potential horror story before we even showed up. A cute young guy named Jake level-set us on their expectations and made us read (and sign) a special "Burning Man" agreement. I asked him what their experience with Burning Man rentals was and his response was "wrecked." He then explained how some people just drop the RV off without cleaning it and that it takes hours to make it rentable agin. To those people they charge as much as $1,000 as a cleaning fee. His pragmatic advice was to show we really tried to clean the playa off the RV.
We did really try. In fact, four of us collectively spent about 20 hours trying to clean off the dust. But we knew it wasn't close to perfect. When we dropped it off, a woman did our inspection. (I was hoping for Jake). She was as pragmatic as he was. She pointed out a few areas that needed attention. I got defensive at one point and she cut me off. She said "I'm not saying you didn't do a good job. Given where you where, this is excellent, but I do need to charge you a bit to make it roadworthy for the next customer".
Our extra charge was only $75. We paid it happily. In a world where some many people try to take advantage of you, I felt the folks in Henderson were fair, balanced and nice to deal with.
Jake told us he has never been to Burning Man, but he hopes to get there some day. He is welcome to take a bunk in our RV next year, if he can call in sick to work for a few days next August.
