Most new vans have a pressure hatch presumably to keep out the dust while travelling.As our van is a pre pressure hatch,if I put the front vent of the 4 season hatch onto rain would this work the same?
I wouldn't do it as I've found the four-season hatch to be fairly fragile. Maybe you could just do the back flap, but definitely not the front one. It's very flimsy if mine are anything to go by. I don't use the pressure hatch at all. I did find mine leaked this last trip, so I had to put a tarp on the bed with a towel to soak up the water. I don't know where the leak is exactly, as it only happens when I'm travelling, not when I'm parked. What we do with these caravans I think is not the intention of the builders and dealers. They look really pretty in the yard, but put them on the road and all the pop rivets pop loose, and the staples fall out.

Chriss, the difference between water leaking when travelling vers when parked is the amount of wind pressure on the seals /windows etc,same with leaks in cars you can hose the all day & not leak but drive in some rain & you have a leak. I have chassed these leaks many times over the years at work & can be very hard to find.

Using the front flap on the 4 seasons hatch will work for awhile, butwouldn't attempt it if you value the flap/hatch as they have a habit of flying off when supjetced to high velocity winds. Cheers, ozjohn.

I concur with others here the four season vent is not made to take the strees of the wind past it while traveling (even if you go slow).
You can install a Scupper Vent yourself and this I have done just find an apropriate section and ensure when you start to cut a hole do not go through a cross frame.
I then also made a little velcro fly mess on inside to stop fourign objects if they occur geting in.
