My 267bhs has tank fill on curbside and water hook up on opposite side, is there a way to fill from hook up to disconnect hose rather than dragging to other side of camper when night time lows are below freezing and highs above?
Not really, unless you do some kind of modification. Just keep your fresh tank full while you're parked and top it up each day or two. I agree it seems dumb that they would design it that way - on mine the two ports are side by side.
Once the yard dries out I'll take the panel off and figure out how to put in a bypass that fills the tank and install a 1/2" solenoid where I can just flip a switch and not have to pull the panel off!
