Congrats on the TT!!
Even though we have a pop up and a tent/pop up site booked, our pop up has both a grey and black water tank.
We dry camp in our pop up - have for a week and half at a time - and use a portable waste tank to dump instead of moving the pop up. The pop up has a 20 gal grey / 9 gal black.
I do all of our dumping for the pop up. I love the Rhino sewer kit (orange connections) that I have. I also have a clear Rhino elbow that attaches to the Rhino hose. I can see things drain (black tank, grey tank then water flush) and the clear elbow has a place to attach a water hose. I also have an orange water hose as opposed to the white drinking water hoses - so I know which hose is only to be used with dumping and not to be connected to city water.
I got a Barker 4 Wheel 25 gal tote tank with solid non inflatable wheels. It has a white metal handle that is removable for storage and the handle will attach to your hitch - so you can drive the waste tote to the dump or another empty site (at the Fort).
I got the blue Barker 1. The wheels don’t have to be inflated so one less thing that needs the air pump 2. 4 wheels (as opposed to 2) makes it stable and easily drivable attached to tow vehicle. 3. Has a valve on the waste outlet - important to control the waste - and no leaking - And a floaty on top to tell when the waste tote is full. 5. The waste outlet valve is low - easier to empty. The other brand the waste valve on the tank was higher - making it harder to get everything out. And I didn’t want a sludgy, stinky waste tote.
Waste totes aren’t cheap - but I’m glad we have ours. It will travel down in the pop up.
I plan on looking for empty site mid week to dump in (probably wed/thurs). And again at the end if a site is available - I figure weekends they are harder to find.
I’ll just use my Rhino sewer hose and clear elbow to dump into the tote tank (it does attach to the Barker tote and is SECURE! no leaks). Then hitch the waste tote to the Expedition, drive to empty campsite. Use Rhino hose (no elbow - won’t fit) attached to sewer outlet valve to dump at site and take orange water hose to rinse out tote so it doesn’t smell. Hooking the orange water hose to the campsites water connection.
Plus I always carry a pack of purple nitrile gloves. Easy peasy.
But - good luck to getting a bigger site! Hope to see you there in October!
