I needed to get some more airflow into the GFC while driving and when camping. Driving for the dogs and camping for whoever is downstairs.
I considered the positive vent style horse trailer vents like a lot of people have done on here, but needed something that could create more airflow especially when stationary. I also like to be able to see out the sides if I end up keeping the lid down when hunting.
I bought some RV windows off Amazon and went to work. I have done windows on both the Flippac and Harker in the past. The Flippac was tough because the sides were partially curved and tough to cut it the right size and the Harker was tough because I had to hold the window myself and trace it myself to get the hole right. The windows I bought came with a cardboard template which was a game changer.
I opted for center of the opening between the cross bracing. It put it fairly in the middle of the outside too.
I used a Dremel tool to get the corners and then used an oscillating tool with a carbide blade for the rest. I have used a jigsaw in the past, but found that as I cut, the shavings would get caught under saw and scratch the finish. I could have taped it all up, but this approach worked really well.
Then I filed all the edges, treated the bare metal with a metal primer and then used some foam seal tape, and silicone and set the windows.
All in all, super happy with it. I put one on each side to get some cross breeze going. It also really opens up the feel when down stairs, which the kids love too so they can see out and still be buttoned up which will be nice when winter camping and we have a heater going.
