Normally in the dump station area in the campground is a fresh water hydrant off to the side to fill up your tanks, but don't use the one next to the crapper hole it's to wash out your black water tank. Or in the campground in between the camp sites you will find a hydrant that you can use, you will need a long filler hose or stop on the road by it. But they have the auto off handles so it takes two people one to hold it open and one at the camper to hit the hole
X2. Make sure you sanitize and rinse your tank & water lines several times before you fill them. Several threads on here about doing that. Always use a potable water hose (not a garden hose) for filling your tank. I use a blue hose-end filter on the end of the hose when filling and water tastes great. I keep it in the refrigerator between fill ups, to help retard the growth of bacteria. At most State Parks, etc., the green
water hydrant is the fresh (drinking) water, and the red
hydrant is for flushing your black tank. The dirty little secret is, they both come from the same well, and both have back-flow preventers. You just don't want to insert a hose into your fresh water system that's been used for black tank flushing.
As for hauling water, I generally haul with a few gallons in the FW tank, just for flushing the toilet & washing hands during travel. It's also come in handy a couple of times when the CG fill station was either down, or too busy. I was able to overnight with what I was carrying. To be honest, a full tank of water in your unit would only weigh about 120 lbs. (about the weight of an extra person). It won't affect your gas mileage much (if at all), but with your limited CCC, I can understand your not wanting to travel with a full tank.
A ton of people here on The Forum have X17Z's. Feel free to ask any questions you may have. Someone's sure to come up with an answer.
Enjoy your camping adventures!
