One of my vents, those that are on the upper front and lower rear side of the toy hauler broke. The ones you manually push out and pull in to let air flow through the toy hauler.

Where can I buy one and are they difficult to replace?

I think I have a good idea of what you are looking for but I don't see one listed in my catalog. A picture would help.

Bottom left corner!

Here and Here are the closest thing I found. They are also called horse trailer vents

Thank you sir!

I found the best thing to do is go to the original manuf. and order the parts from them, perfect fit everytime, no mock up. jmo
