RV type roof top vent? There is a flat section on our roofs for this. Someone installed one in their van and did a nice write up recently on the other forum that must not be named. I'd link you to it, but rule are rules.

Hmmm, you know what I'll ask permission to add it to the AstroSafari Data Repository on CarDomain.

We can link to other sites, but the other forum that can not be named is strictly off limits. You can't even post the initials to the other forum that can not be named.

Roof vents are excellent for camping, most RVs have them.
