My wife and I recently purchased a brand new destination trailer to spend the summer in with our kids. We chose our "permanent" campground based on my wife's parent's presence there and price rather than amenities or practicality, and as such, the campground is currently more of a dry camping area after the Missouri River floods of 2019 (no direct water or sewage hookups). To accommodate that, my wife decided to purchase an enormous (no idea the size) water tank but at least 3-4x the size of our fresh holding tank. And also purchased a sump pump to transfer the water from the large external tank to our holding tank as needed. It works ok... but not ideal.
My question is, since my trailer has a city water connection, does anyone know if it'd be possible or even a good idea to try to hookup the sump pump full time as the city water connection of our rig? Obviously it won't work full time as a feeder to our holding tank as the tank has a overflow fail safe that dumps extra water that won't fit in the tank and we'd just end up with everything from the external tank on the ground.
Appreciate any insights y'all can provide.
