Hi everyone. Recently I got my promaster 136 wb hr , converting to camper van. Need some help from you. thinking to installl windows. Can't decide Fixed vs T-vent ???? could you give me some suggestions . do T-vent windows worth spending extra $$$, considering I will have maxxair fan ?!?!?!? Thx...
Just weighing in on the CRL experience...I installed the vented OEM look on front diver's side. I have a 159 wb. I cut part of the shipping box to size of the window and then traced the frame inside that. The cardboard 'window' fit well so I taped it up on the side of the van.
Note I had a smaller generic CRL flat slider window in that space initially but I hated the cripping or waves created around it in the van skin (probably due to my STUPIDLY clamping directly agains the side of the van). Anyway in the first shot you see the hole from the original window.
It all went pretty well but I note like others that the factory lines or stamping (inside) for a cutout were off for this CR Laurence window. The window looks perfect from the outside and it fits great after the install but you can see from some of the inside shots how it doesn't match up with the factory - so don't just cut according to the lines you see on the inside of the van.
Another thing I did which was probably unnecessary was add some butyl tape on the frame where it gets pulled against the van skin. I don't think it creates a problem and may help prevent water ingress. So far so good.
I'm not handy and a noob at all this so want to add I've appreciated all the threads and pictures on all aspects of camper builds on these vehicles. So far I've only done a Maxx fan and this window. For the fan I added a wood framework that the clamp ring will screw to once I have a ceiling.
For the OP I want to point out the Fan Vent can do very little or nothing unless there is a way for air to enter or exit for the vent to move it in our out. We have awning (like the T vent but one single opening on the bottom half) from Kinro in the side and rear on the drivers side of the van. We run our Fantastic Vent pushing air out at night and open the awning at our head of the bet to get a nice gentle breeze coming in and little noise as our vent is near the front. Get the T vent.
