Does trailer have to be level when de-winterizing?

Dana

Getting ready to do this task.  My 2021 tab 320  needs to be pulled over to the water spicket and won't be level.  How much will this affect the de-winterizing process?

At worst, the fresh water tank will not completely empty when you are done sanitizing.  As long as you have rinsed out the bleach water, you can then open the fresh water tank drain valve  and move it back to your storage spot, raise the tongue and it will help empty the tank.

The first time I drained water from my 2021 320S I got another gallon out of it when I tilted it back. To completely drain the gray tank I have to tilt it toward the drivers side.
