First off assume that the gauges DO NOT work properly. don't rely on your gauages just monitor how much time you spend using the trailer. don't waste your time trying to get the gauges to work....they won't--ever.

but if you want monitors that work.... https://www.garnetinstruments.com/rv-shop/

Rule of thumb on black water tank...you can go about 2 week with 2 people using the trailer.

I assume your gauge monitor has 2 grey tank, one black and a fresh tank. probably the most accurate one will be the fresh water tank. You do not have 2 black water tanks if you have one toilet--which goes directly into the black water tank.
