When you own an RV one of the things you have to deal with is dumping the waste tanks at the end of your stay in a campground. This is generally not a big deal, you pull up to the dump station, usually located along the driveway on your way out, hook up your waste hose and dump your tanks by opening the 3" slide valve.
But what do you do if you go camping somewhere other than a campground? Well, south of the Mason-Dixon line you will find numerous facilities where you can dump for free or for a small fee, but such services seem to be a whole lot rarer up North. In my case we often take the RV up to visit my sister and her family in Maine and park in their driveway. There's really no conveinient place to dump when we return.
So I decided to see if I could cobble something up to make this task easier.
