Dumb question,

I am a strong believer that the only silly question is the one asked multiple times lol with that being said my ears are wide open, does the fill.neer to.be placed somewhere higher that the fresh water tank or will it defy gravity???;)

A normal fresh water fill will need to be above the water level in the tank.

Gravity sucks........

Pressurized water, like from a garden hose, will flow up hill.

It's probably less trouble in the long run to be above. Anything below the level of water is another possible leak. Free flowing water from above will fill faster than water from below fighting the tank water pressure provided by gravity.

That being said my experience in water tanks and pumps is from hydroponics not in rv/skoolie. I filled a 275 gal tank that was 6ft off the ground from below because that's where the fittings were. the elevated tank was to gravity feed water to the garden.

your tank inside will have the filler at the top, the outlet on the outside you are suggesting might be lowers than the spot on the tank. it would still technically be filling from the top. couple feet wouldn't make a difference. I hope I am picturing this correctly.

Yes where I "want" to put my fill to tank is just going to have to be different that where I put it at in relation to the tank that's all... I appreciate the info thank you again

Older RV's used to use a gravity fill type system that placed the fill point higher than the tank. As near as I can tell, this has changed (at least on the larger RV's) to a pressure fill system that is located in the wet bay (usually convenient).

In my case, I installed a hose reel in the wet bay that is permanently connected to the plumbing system (thru pressure regulator, then filters, then to a valve that is either the 'system' or 'tank fill'. I pull out this hose and connect to whatever is available - no need to attach any extra stuff (pressure regulator, filter). Very old photo but gives you the idea...
