As for water, it all depends. How long will we be gone and will we be in territory we know.

If we will be gone a long time, I fill the water tank. I like having water we are used to available, if we need it. I also fill the tank if we will be traveling with many folks.

If it's just the wife and me and we are traveling a short distance (Florida Winter camping with friends) 1/4 tank is fine.

I have 105 gallons of freash water capacity. At 8.3 lbs/gallon it comes to 872 lbs. I have never been able to determine the cost (fuel) to carry the additional weight. At this time, I feel the weight is an insignificant hit to the MPG. The items mentioned in my OP make the big differences.

My toad weighs 5074 lbs street weight. The best I can determine the toad costs me .3 MPG. Consider carrying the amount of water you are comfortable with and forget the effect on MPG.

On the topic of A/C, what has been previously posted is also my experience. Consider keeping the coach comfortable for everyone onboard. My gen set takes about 2/3 gallon per hour. It is not enough for me to be concerned about.

We've found that it helps the dash air greatly if on hot days we use the roof air to cool down the interior either on shore power or generator before we start traveling down the road and that the dash air is then able to maintain a comfortable temperature in our rv. The dash air is not powerfull enough the cool off a warm rv by itself so if we don't do this it stays warm inside no matter how long we leave the dash air on. I've heard of some people hanging a curtain across their motorhome just behind the driver and passenger seats to reduce the volume of area the dash air has to cool but have never tried that. Precooling our motorhome seems to do the trick.

A lot of factors will come into play. Weather, hot or cold. Ground mountains or flat land. Are you at max weight or running light. Do you have a heavy foot or light foot. 9 is do able but 7 to 8 might be more likely!

Mine is a 26' daybreak, and I think I'm getting about 9=10 mpg. I will know for sure later this summer/fall. A friend of mine has a 34' bounder and he says 7 mpg without his toad and 5 mpg with it. YMMV
