I have multiple methods depending on the rules of the campground. In general I use a 20 foot cable that I attach 1 end to my RV, the other to a stake in the ground. I then attach 6 foot leashes to the cable. The dogs can move between the RV and the stake. They do get wrapped up occasionally. A final method I use involves using a vibrating collar with remote. When the dogs get beyond where I think they should, I call them, if they don't respond, they get a buzz (like your cell phone on vibrate). This is the best method of the two. The dogs are now trained to stay close and not run off...
