Hi Deborah and welcome to the forums.
I'll let others respond to your vent issues, but thought I'd share with you in a slightly different way.
Here's an all ladies camping group organization that have chapters all over the US. They are a great bunch of people as we've run into a couple of their camping groups over the years.
Their moto (use to be).... No pets. No kids. No men.
They are an awesome group (if you are a lady!)
Sisters on the Fly - click here.
You might check them out and see what they have that might help alleviate some of your concerns being solo.
Good luck, and again! Welcome!
Here's a link to some of their camper images so you don't have to actually log into their web site to see them. Pretty cool campers.
Clcik here
