Ventilation

[Gold Coaster]

I have a T4 that is a part campervan but doesn't have a pop top so it's hard to have adequate fresh air on warm nights without having windows down (mossies and security!). Looking at cutting a hole in the roof to put in some form of ventilation but am a bit wary of doing this! Has anyone had a go at doing this? Thanks

My Father had just done a conversion on his T4. He put in a four seasons hatch in, it is about 600mm x 600mm. He carefully cut it out with tin snips and a jigsaw, did a great job. I can take some pictures if you like.

Would love some photos thanks, showing both an inside and an outside view if possible. Also I'm interested to know how well it works at moving air (does it have an inbuilt fan) and how high it sits proud of the roof as I need to be able to get under 2.1m.

Hi Gold Coaster,

Here are the pictures, inside and out. You can pop one end up as shown or the whole hatch. They're is a fly screen that you can slid in place after popping up. The ventilation is just passive, but is most certainly adequate.





Hope this helps,

Cheers James

hey mate,

there is an adaptor to hold the tail gate open a few cm without making it possible for sb to open it from the outside, doesn't work with barn doors. It is a low volume product made in germany.

PM me if you are interested and I can google it for you (might take a while though, saw it a while ago)

Thanks for great photos. The hatch is a really neat fit between the roof ridges. I was originally looking at a smaller type hatch (350 x 350) but I guess the bigger the hatch the better the ventilation. I suppose my only concern with cutting a hole that large would be whether or not it would effect the structural integrity of the roof?

Hi, yes I've seen these on the Just Campers site (tailgate vent lock). They look like a good idea in that you can still lock the tailgate but the only problem is that the bugs can still get in! Probably would be useful though on a hot day when you have to leave the van standing in the heat while you are away.

I am pretty sure the hatch fits in between the strength members, so roof integrity is well maintained.

Hi guys as some of you would know I fit sunroofs for a crust we encounter cross roof braces constantly . The T4 is a sweet model to fit a sunroof into as the rear sections have the cross brace only at the high points cutting between these will not affect the strength . My old dearly departed T4 had a fully built in sunroof at the front section and I removed the cross brace for that one but the sunroof and its supports more than made up for its loss . I then fitted an electric external sliding roof into one of the back sections easy as pie to do no brace to remove even fitted a remote switch up at the dash so I could open it with out any one in the back doing it .

When you do cut the hole, DO NOT use and angle grinder.
A friend did this on her van and she had to get the whole van professionally polished to remove all the metal splinters that etched into the paint work whilst hot and then started rusting causing a major issue.
she was advised the best method is a metal nibbler.
Good luck
