From what I can tell it looks just like any other that you would see on a mobilehome or camper. But I just wanted to know before I buy something that doesnt work. Is there anything really trick out there?

My Van

 

Just replaced one on a 65 van. Measure vent size and head over to the RV dealer of choice. They fixed me right up.

 

Ford did not offer a roof vent as an option, so whatever is on your truck must be aftermarket.

 

that does look like an aftermarket vent you have there.

ford actually did offer a roof vent, only problem was you had to order a special equipment package to get it! that and you had to order about 500 vans along with the special package! biggest user was ma bell and pacific gas and electric.

[just a worthless little tid bit i have picked up over the years! i guess i should realy get a life huh!]
