Some say that if you bring food somewhere, bring enough for everyone. Personally, I disagree, because people are usually only interested when it's cookies or donuts. I figure if they want cookies, they must have the broccoli first. :D
Same thing with rv freeloaders. Sharing in the use of the rv amenities is the cookies and donuts and the broccoli is the expense of the fuel and helping with maintenance during the trip. No broccoli, no cookies or donuts. :p
Also, nobody will ever care about your stuff as much as you do, so to me, it would be an easy "get your own!" Otherwise, as another poster said, be ready for Judge Judy when things go wrong.
