As far as ozone machine, you have to know what you're doing a little.
You never want the machine *in* the area you're ozoning. The intake always needs fresh air to pull in. I usually open a window, wedge the machine in, and use cardboard to close off the rest of the area.
You want the ozone running for a while (half a day), and then let it sit for a day at least before running it again. The material you're ozoning matters a lot. Thick cloth material/chairs will take much longer than concrete/wood/less porous surfaces.
The issue would be air movement inside the rig. How is the ozone going to circulate everywhere? Put a small fan to blow the ozone around. Make sure you're getting the ozone everywhere you can.
In my car I did 4 hours ozone, let sit 12 or so, ozone again.
After you're finished, depending on how many cloth surfaces you have, it could take a very long time for the ozone smell to completely dissipate, which isn't a huge deal generally.
