Not a saint, but I should still be able to help you out! I believe you are asking about a standard square roof vent on your trailer, and you really just need to know two things - the size of the cut out of the vent opening and the (approximate) depth of the opening. Good news is, square trailer vents are almost always a standard 14-1/4" x 14-1/4" (give or take a smidge), so that's likely what you have, but you'll want to verify. If if is, you can use either a vent without a fan or a vent with a 12 volt fan:
- Ventline E-Z Lift Ventadome Trailer Roof Vent # V3092-601-00
- Ventline E-Z Lift Ventadome Trailer Roof Vent w/ 12V Fan # V3094-601-00
Then you just need to know the depth (the thickness) of your roof to get the correct garnish, which goes around the vent. It doesn't have to be exact as you can trim the garnish; just get the closest dimension:
- Ceiling Garnish for Ventline Roof Vent - 2-1/8" Leg # VA0445-34
- Ceiling Garnish for Ventline Roof Vent - 3-1/8" Leg # VA0445-35
- Ceiling Garnish for Ventline Roof Vent - 4-1/8" Leg # VA0445-36
- Ceiling Garnish for Ventline Roof Vent - 5-5/16" Leg # VA0445-37
Then to install the vent use Roof Vent Installation Kit # 344270KITW.
