Fresh water tank fill problem

I have a new 2015 Heritage Glen 282rk, my fresh water tank is 52gal. cap. I can only get about 25 gal in it before I start having water come out the vent,

Are you using a "hose extension" that goes about 18 inches into the neck ?? Most are clear plastic tubing with their own shutoff valve to regulate the flow.

That helps a lot.

I can generally go full blast to about half full and then must throttle it down to half flow or less for another 15 minutes or so. I also suspect that my tank only really holds about 80 percent of it's advertised capacity......and splashes a little bit out of the vent when going down the road too.

While it's a common problem, if you continue to only get a 50 percent fill......see your dealer.
