Welcome to the Site Joe Bob...
Approved Dump stations are at a large variety of locations depending in which state you are at, you may find them at State sponsored Rest areas along the Highways, Most Public campgrouds have Dumpstations that you can use .... most charge a small fee...1-3.00 depending on the site, Some Truck stops also have dump areas. Start watching the highways for the "camper/TravelTrailer" sign with the uhm..... triangle to the rear... As you are new to the RV world don't be afraid, or too embarrased to ask for assistance from a fellow rv'er to kinda show you the ropes. I think you will find that 95+% are great folks who will gladly assist.... at least with the supervising part....
