So, our children that sleep in the bunks in our 26BHS have complained about how stuffy it is in there. The bunks have three sides enclosed and the fourth side about 70% enclosed. I have been scratching my head about how to install some fans that would not require a bunch of mods to wire in - either to 12v dc or 110v ac. I just didn't want to tear into a bunch of stuff to wire them in. I found battery fans, but based on reviews, battery life with them running on high wouldn't even make it through a quarter of a night. We have enough stuff that runs on AA batteries and I didn't want that added expense
I finally had an aha moment last week and bought the following:
1. Two battery/micro-usb powered fans with clamps. These will run w/o a battery in them if connected to USB power!
2. Two usb 110v chargers - dual port chargers will reduce output when two devices are connected, so I opted for separate chargers
3. Two 15' micro-usb (android style) charging cables
4. One power strip
5. Some self-adhesive wire clips for keeping the wires tidy.
Between the skirting under the bottom bunk - pretty thin luan plywood and the wall, there was enough of a gap to easily poke the usb cables through w/o drilling. I plugged in the powerstrip into the fridge outlet in the storage bay below the bottom bunk and plugged my usb chargers into that. Clamped on the fans, routed the wires and installed the self-adhesive clips and voila - fans in each of the bunks. Everything set me back $80 on Amazon and took me all of 15 minutes to set up.
We are headed out on a family vacation tomorrow, so we will have a chance to give these a good workout and see if it solves the problem.
Fans are adjustable with 4 speeds and are fairly quiet. Some pictures have been pasted below:

Hope this helps! I will report back on how well it worked when we return home.
