ford truck guy, yes the camper will stay on the river lot and not moved unless it is going to flood. I am not worried about taking the tanks with me when I leave to empty them, just wanting something easier than carrying 2 or more tanks with me every time we come and go. Old-Biscuit, the river is actually a clear river, one of the cleanest in my area. We will only be staying up to 3 nights at a time so I was thinking just trying to filter the sand would be good enough to at least rinse off with during the summer months. I have power on the lot so that is no worry's. Just need ideas for an easy pump and filter system. My camper has a hot water heater, but I think its just plumbed to all empty out of the same spot on the camper.
