Helpful Expert Reply:

There isn't a guide to tell us how large the round vent is in your 2021 Nucamp T@B 400 so I'll first need you to measure the cutout hole diameter so that we can confirm a proper fitment. For example, the MaxxFan Dome Roof Vent w/ 12V Fan # MA00-03812B you were looking at requires a 6-1/4" diameter cutout hole in order to mount. This fan comes with a bug screen and rain shield so that it can be open the whole time you're setup at your campsite. You will need to pick up some butyl tape # AL28FJ and self-leveling sealant # 34427034145-1 in order to form a proper watertight seal to the trailer roof.
