Replacement Trailer Roof Vent Cover with Ventline AS-13, M-V101, ANS. 326.1, DOT. 733 on It  


My broken vent cover is 14x14. the vent opening is 13x13. The motor home was manufactured in 1995. On the old vent cover it has the following information: Ventline AS-13, M-V101, ANS. 326.1, DOT. 733. Do you have a replacement cover?


Expert Reply:

Based on the information that you have provided you can use Ventline roof vent lid # BV0554-01 for white or # BV0554-03 for smoke. These covers have the same numerical information as what you have provided except that it is likely Z26.1 and not 326.1 on yours.

I have an Airstream Travel Trailer which has two Ventline 12 volt powered round exhaust fans installed. One of the vent caps has been damaged and needs to be replaced. The vent cap is black in color and has the following listed on the top side of the cap. AS-13 M-VA 204. I do not find this number when searching on the internet. I do find a cap in smoke that looks to be the same except the color. On your site the part BVA0502-03 looks like it may be the same but does not have any numbers that match mine. Your help in letting me know what my options are will be greatly appreciated.

From what I could find it does look like the Ventline Replacement Dome # BVA0502-03 may be the right cover for the existing model in your Airstream. To be sure you can simply measure the diameter and height and compare it to the dimensions of this replacement (8-1/2" diameter, 1-3/4" height). If it matches it'll work well.
