Our property (large sports venue) has multiple camping lots that are used for event weekends a few times each year. We currently separate RV camping from TENT camping, primarily because of the risk of Carbon Monoxide poisoning. I have been asked if one of these lots can have both RV and TENT camping if a sufficient separation is established between the two. Before I approve an exception to our rule, I was wondering if anyone else has seen or developed any rule or regulation about this? Would the fire lane be enough (in your opinion), or should we go bigger (30-50 feet)?
