I always wanted to get one of these for the gravity fill when I had the pup,Question…how well do they work going “uphill”. Long ago I had one for my fish tank worked great for sucking water out of the tank but it was not able to work in the other direction to put water into the tank unless you lug the bucket above the tank. im Hoping to avoid having to lift a 5 gallon bucket of water.
i have a portable outdoor shower that has a small 12 volt submersible pump. fits inside the 8 gal aquatainer and transfers water to my fresh tank - just take the shower head off and stick it into the fresh tank inlet. can plug into the car - or i also have a small Inverter it plugs into so i can plug it into the camper outlets (or the site power pedestal). so small, it fits into a drawer in the camper.Well I have most of what you referenced except I also have a Y connector. So I can still access the water from the pole without having to disconnect the hoses. With that said it's rare for me to actually get a site that has water hookups and if I do, they have been shut down for winterization. Critical thing for me is to also have a bucket onsite so that I can fill my tanks from community faucets that are inaccessible with the camper. Many places I go don't have fresh water at the dumpstation. Unfortunately I'm still using the funnel method so next on my list is an external pump. Even crazier some seasons I don't even bother dewinterizing. I cook outside and wash dishes outside anyway. Guess I still have a tenting mentality.
