I have heard of the bad fit of these windows before, and decided at the time they weren't going to work because of fit. Yours has convinced me to stick with the original.

Our van is a 170" 2500, so maybe it was the first of that model with full glass in a cargo. Doesn't matter, i still love having all the glass. Maybe if i did it again, i would do the CRL's all around so they match up and open a bit.

Just read through most of the posts on this subject for the first time. If cutting holes in the vans is so critical, why would Mercedes be careless on using the adhesive to glue the braces to the sheet metal sides. My 08 144" had at least half of the structural supports unglued. Others were partially glued. I used a full tube of adhesive to glue all the supports to the sheet metal where they had missed. I suspect all the discussion is lawyer based. Someone should explain how the van will fail if you cut holes. Cutting holes will reduce the structural integrity. Will it reduce it enough to matter? If you keep the van sunny side up, it probably does not matter. If you put it upside down, then it will collapse more with window holes than without holes.

Does anyone have anything to add to this thread. I'm getting closer to adding factory windows in my 2008 3500 ext mega roof. Thanks, Ross

Page 81 I would guess is the definitive answer on retrofitting rear glass...

http://www.ourexcellentadventures.co...B2010Part2.pdf

Do not retrofit windows on Cargo vans delivered without windows, except in the following areas: rear doors & sliding doors. For Cargo van conversions with specific application windows (RV, shuttle bus, etc.), you must order the Cargo van either with windows or option “window opening without glass” (Option F27 fleet only).

That's my take on it. Common sense is rarely effective in a court defense.

when those holes are not filled by something.

As you indicated previously, it will matter if lawyers get involved regardless of the structural integrity.

Perhaps? You can't completely discount the strength of the window frame and any added supporting structure... oops, yes you can if lawyers are involved.

I know I don't have the inclination or enough money to pay for the engineering necessary to prove it all one way or the other. My opinions and worth everything you'll pay for it. vic

I did think of something else on the subject. Recently someone posted a picture of a Sprinter with the sliding doors on both sides. How can you put that big a hole on both sides and then say adding a window is a problem?

I don't want CRL's.... where can I get the best price on the OEM windows? Thanks, Ross

You might as well try to herd cats as to expect to get a definitive answer Ross.
That should wake someone up ...
