I too have this issue. I live in PA but store my camper in a woody area at a campground in VA Beach. EVERY time we go back for the weekend to camp we end up catching at least 20 or so.
Anybody have an idea how the little buggers are getting inside? I know they can squeeze in just about anywhere but I've wondered if there is a preferred entry route. I personally wondered if they are coming in through the A/C.
Takes time to do but can also help with many kinds of pests:

Seal all cracks around windows, doors, siding, utility pipes, behind chimneys and underneath the wood fascia and other openings with high quality silicone or silicone-latex caulk.
Remove wall and window air conditioners; weather stripping around doors and windows may help. Repair broken screens and windows.

Specifically for A/C units in RVs I'd think that in addition to caulking, a fine mesh screening material placed over the venting would do well if you are concerned the bugs are entering from that portal.
