Class B RVing. What to Expect..

We've never had an issue with site stealing. We camp out of a B. Our B is for sleeping and shelter during sever weather. If we plan to spend more than one night at a given site, one of the first things out is our kitchen/camp box, then the light/power pole, followed by coolers and other assorted camp stuff. The camp box holds all our utensils, cups, bowls, spices and virtually everything needed for cooking. We do all of our cooking outside. The light/power pole uses the shore power and bring it to the picnic table and provides light and a handy power source when needed. Having these things established on the picnic table is a clear sign that the site is taken. Besides we always have the payment stub/receipt.
If we are one nighting it, nothing is taken out. Coffee pot is at the ready, but inside. Just our experiences.
