Where is the valve to drain freshwater tank

Where is your freshwater tank? Look around the tank inside the RV or under the RV under the tank. It will be right at the tank. The outlet of the drain, at least, will be under the RV. The valve will be right above that.

Crawl under. You’ll find it.

Some times it is a cap instead of a valve.

look at your FW fill port. The drain for the tank will be under the 5er very near the inlet. It will have a cap or a valve. Next to it may also be a vent/overflow line with no cap or valve. It May not have a vent out the bottom but a vent at the fill valve Incorporated within the fill valve opening.

There is no way anybody can help you with the information you provided. Provide the complete make and Model of your camper. Then somebody that has one can tell you where the drain is.

Owner's Manuals are really interesting.

Look around the sides of the fresh water tank, near the bottom of may actually be on the bottom of the tank, depending on your individual model. Ours is near the water pump, but a separate fitting off the tank, it then has a separate valve before leading to the 1" drain pipe to the bottom of the RV. Our old trailer just had a screw cap on the drain pipe.
On ours, the pump and fittings are on the opposite side of the RV from the fresh water fill and vent fittings.

Your rigs new enough that you should be able to pull into any dealer who sells coachman and find someone who will know.

statements like this have no place here. If you can't be helpful maybe you should not post anything...

There is virtually NO owners manual that would have the location.
Nearly all RV owners manuals are generic, with no model-specific information.
