How do you know when it's full? Meaning, if I have a 50g black tank and this is 21g what happens then? Thanks in advance.

I open the 3/4” hose opening and look straight down as the tank fills. If it is dark, I use a flashlight but I try not to fill it at night. Having the cap off the hose opening also relieves the pressure in the tank as it fills. Grey water is a little easier to see since it has bubbles on top as it fills.

Do I need a trailer hitch to tow this behind my Jeep?

You will need a ball type hitch.

is The hook up to empty standard? There is a truck that empties other campers holding tanks. Will it be able to empty this?

yes, but it is portable so you would not need to have a truck come to your campsite. you can empty the tank yourself at the dump station. If you still plan to use a service I would not purchase this item, unless you are looking to add capacity to your tanks.

What are the deminsions of the tank with the wheels on?? From the ground to the top of the tank when it’s sitting on the metal support to fill it

For the 15 gallon unit the waste inlet with the 90 degree elbow attached is about 13.5 inches from the ground to the low point of the inlet. My camper drain fitting is normally only 8.5 inches off the ground. I'll have to play some games to make up for this 5 inch negative slope. I can lower the tongue jack and place the camper on leveling blocks to get these 5 inches back. Someone suggested digging a hole... If you dug holes for the wheels and the front support "foot" you could lower the tank about 2.5 inches without digging out the entire footprint.
