I sanitize our tank a lot now that it is warm, probably two times already this year. Maybe overkill, but I want to postpone dirty tank issues for as long as possible. I use little plastic pipettes and add four of those, which I estimate to be about 2 T of bleach. I don't like using the pump to drain the tank but will do so if I am in a hurry. Today I was draining the tank and it was about 80 out. I ran about 5 gallons out to make room for the hot water to drain, and the pump was slightly warm. I've found on my 2018, the hot water will not drain unless you open up the faucet to let air in.

Thank you Sufi .
I purchased my 07 Hawk second hand and didn`t receive a manual .
Most of 2017 FWC instruction manual still applies when operating the storage and hot water tank system and clears up any confusion I had.
Cheers.

I've also used the pump to drain water into the sink when in a hurry. But I try not to run it too long. I'm sure replacing a pump is a bigger deal than waiting (but impatience still comes up!). It takes a really long time to drain. On trips I drain the last day while driving. It really helps to have the front of the truck uphill, which seems to drain more. But I also drain with it level in case that helps.

When the tank monitor showed one red light “E”, so I assumed it means empty, and I continued to get water until the pump does not shut off anymore. Then I added 14 gallons to the tank and the monitor showed four red lights.
So, good thing that I was bored and have some time and decided to take a look st my tank...
After removing about 30 screws, including one with square head to enable the cover over the tank to be removed...couldn’t FWC hire someone from IKEA to designing easier way?
Anyway, I measure my tank to be about 24x14x13, and these are approximate as I can’t get precise length due to access to one end, which translate to 18.9 gallons when cu inches total is divided by 231. I see the tank is full up about 2 inches below the top but the monitor shows it is full after adding 14 gallons from two 7 gallons containers and I could of added couple of gallons more...I usually fill up with hose until water spills out.
I am guessing the outlets at the bottom of the tank is not at the very bottom so there may be couple of gallons left in the tank which the pump can not pump out at level surface. I guess I should be able to test and verify all this by experimenting. Anyone have figure it out how best to manage the tank more precisely? I know now to not trust the monitor. A visual gauge through the front panel would be nice.

I use the Bernard method too, and will again for my new build. And I agree, that the tank size can't possibly be 20 gal. I have a new tank and can confirm your rough estimate on physical size. I have not measured the actual volume with water though.

On my 2018 Hawk, I tested by completely draining, and driving around for a week with drain opened parked on slope, etc. I then timed the filling of a 5 gallon bucket, then timed the filling of the tank. Bucket took One minute and 15 seconds, tank took about five plus or minus a few seconds. Seems like 20 to me. Has not really been an issue, but the rear drain is slow for filling things below about half tank. I disregard the level sensor and go by grey water accumulated as well as an estimate of water consumed for drinking, usually in pack reservoirs so it is easy to estimate.
One time when concerned about having a bit of extra water, I filled the hot water tank from the city fill in addition to filling the main tank. There was definitely a solid 25-26 gallons in there.

I cut a slot in the wood covering the water tank as a sight gauge. Even added LED lights that shine into the tank to make it possible to see the level in the dark.
