Can I Get Away With a Quick Brake Job in a Campground?

We tend to stay at smaller campground (private) which will be found outside of cities. They usually are less expensive, probably dirt pads, maybe stone, and they seem to be much more accepting of someone washing their rig, doing some repair work etc. If you read their rules on their website and it doesn't specifically state no repairs allowed, try that campground. As another full-timer said to us "don't ask, just do it". What area are you in - maybe I can suggest a place.
