My generator is secured to the tailgate corner in my truck bed. When I use it I just pull it out on to the tail gate and fire it off...

If I point the exhaust at my trailer I can set off the Co detector just about everytime. Of course my OFF-ROAD POPUP is not sealed all that much as a regular hard side TT might be.
After I found out I can do this to my POPUP I am now always conscious on where my 2KW Generator is pointed at when being run... Obviously I don't point it at the Fuel Can either...
I guess your camping grounds don't have any generator run time restrictions in place. Most public campground places we go to here on the East side of the US has run time restrictions in place and usually NO Generators after 8PM at night or before 8AM in the morning...
This was my main reason for beefing up my battery banks so I could do all my things I wanted to do off the batteries and only use my 2KW generator after 8AM in the morning when allowed to use it...
