thats what I do now as I used to tent camp until my back surgery and when we tent camped I would rake the sight and then soak it with home defense, let dry and soak again before putting the tarp down then the tent and then spray the inside and let dry while we set up the rest of the sight. it stands to reason I thought, why woudnt I still do it with my RV as there is all kinds of creepy crawlers and some people who bring them with! nothing like roaches and spiders to ruin your vacation.
