Re: INTERIOR WATER FILL
sometimes, when my forward tank isn't full, i hear a gurgling sound from the overflow/air vent over my left shoulder, when i come to a stop or otherwise cause the water to slosh. i don't think there's any way to overcome the noise.
It's not a sprint(er) (unless you make it one), it's (hopefully) a marathon.
