Just know that a bug bomb is rated for use in a house that has several times the square footage as your RV.
There is also a warning on the label on how small an area you can use one can. AND, There is a warning on the label about using it within the location of propane.
If you or your family has any allergy or breathing issues there IS a residue left in the RV that will cause problems. AND it can be a serious problem for pets too. As you will be drenching the RV at higher levels than recommended for "safe" use due to the small space.
I would NEVER use a bug bomb in an RV. Just saying.
