I'm opting for a tightly sealed mini MH, cut, sewn, and sealed on 4 sides down to the ground with extra flaps to burry or put under sandbags. Wish me luck.
I had friends who were first-timers following me in 2001 and the dust storm was so severe as we entered the playa they were seriously going to turn around and go home. It took a lot of convincing that it wasn't going to be total hell all week.
Your nice-looking rig would have been loaded with dirt pretty badly by the time you got through the line, past the gate, through the greeters, and to your camp.
It boils down to whether that truck of yours is as nice as it appears to be (it looks awful nice in the photo!) and how much you care about it getting trashed. If you normally drive it top-down on dusty trails anyway, it won't be too traumatic; however Savannah and Mudpuppy are right about the amount of playa you could take on during entry and exit.
If that's simply not a big deal to you, then I can totally see heading to BRC open-air style.
I've brought art cars (back when art cars could drive at BRC) that had their roofs cut off, and they lived. My "Mutant Vehicle" Land Yacht is open-air, it survives the playa dust just fine. I bring an air compressor and blow it out every day and call it good.
Do they make a folding rag-top for the 4-Runner? Now that would be the shit! Top-down all the way, put up the canvas as soon as you exit the pavement onto the playa.
