This is kind of a gross topic. Actually, it probably isn't common, but is something to be aware of. Yesterday, we discovered a dead dove in our awning arm. We have an automatic A&E awning, that works very well. The wind sensor brings it in when the winds get gusty. It is a really nice feature. 
Anyway, evidently a dove had built a nest inside the arm when the awning was out, and the wind came up and sent it in. I can't imagine that the bird didn't fly away when the awning started moving, but it didn't. I got squished in the arm, and what a mess to clean up. We didn't find it for several days, and it even had bugs in it. The smell was gross.
The day before, we were walking around the RV park where we are staying, and some people were trying to bring in their slide out. Another dove had built a nest on top of their slide, under the slide topper, and they had to get a ladder and a broom to get it out. While this poor man was trying to clean up the mess, the dove was dive bombing him on the ladder! Be careful!
On a similar subject, this is the time of year, when many people get their RVs ready to use for the summer. Be sure to check all the outside orfices for critters. We have seen many nests inside access doors. Hummingbirds like to build nests inside the exhaust vents for your furnace. Also mud daubers and wasps etc. can be behind your refigerator or up by your propane tank. Be sure to inspect your rig carefully.
RV travel should be safe and fun.
