state park and federal park amenities

We started out years ago only camping in national parks with no hookups at all. Over time we evolved to want private parks thinking we had to have full hookups. As we have gotten older, we have come full circle and back to the more rustic places with limited utilities. Because of that, we put a lot of emphasis on tank size when we got our current trailer. This one has 60 gal fresh, 60 black, 60 gray, and 60 galley. For really long stays, we do have a blue boy that i upgraded the wheels on so I can pull it behind the truck. For fresh water, I bought a 22 gallon sprayer from Northern Tool. I did away with the sprayer part and put a water hose quick connect on the pump and a regular 7 way trailer plug on the wiring. It sits in the truck in front of the hitch and when I need it, I just plug it in and hook up the hose. The tank does not say that it is approved for drinking water but I grew up drinking out of green water hoses too before I found out we couldn't.
