new to the TT world
We just purchased a 2019 Catalina 172BHS and are super excited to use it. I have a couple of questions. Do you recommend driving with the water tank full? if not, how easy is it to fill up at campgr...

True, the MPG will not vary much, empty or full. But the more "deadweight" you carry, the more the wear and tear on your running gear -- the trailer's and the tow vehicle's suspensions and tires. So that is something to consider. Not a huge make or break issue, but not irrelevant, either.
I often wondered what that extra weight would do to MPG. When we purchased new, they left the freshwater tank about 2/3 full. We pulled home and was even able to run on cruise control for several mile stretch on the flats with our 1/2 ton.
Since then, we've been pulling with empty tanks and have yet to experience a time when the truck felt like it could effectively pull while on cruise. Last trip we filled about half full and it seemed to pull easier and track better. Not sure if the water is putting weight on the trailer springs to allow it to track easier or what. Lowering center of gravity? Dunno. Our trailer has approx 2200lb cargo capacity so maybe the beefy springs are smoothing out with the weight.
Never noticed a difference in MPG with water on board (grey/fresh/black). Lucky, I guess.
