that looks like a nice unit. when fully open, how big is the opening front to back?

Just subtract about 1 inch for the frame all around it.

I have to measure it to give you the exact number.

Am taking of on a road trip soon, so probably wont happen before Monday. Sorry!

nice! so many of those only open about half way.

I have 2 of the Webasto power sunroofs that i haverelaced for a conversion mfg. Customer complaint was a leak. MOST times its NOT the sunroof that leaks , its the seal between the sunrof ad the roof that breaks down over time. THIS mfg. chooses to replace the sunroof ( OF COURSE THEN the leak is gone) I have put these ( "defective") units in my vans thru the years and have NOT had a leak....EVER. Sunroofs....as a HOLE ( pun intended) Ive NEVER been a big fan of ( because they WILL ALWAYS leak eventually)but i decided to put one in my demo ( 09 Chevy)and i DO like it ,,,,but really i could take it or leave it. The MOST COMMON mistake folks make is NOT PROPERLY maintining the sunroof seal.DO NOT use vasaline to keep your seal "fresh". Vasaline contains petrolium , which WIL BREAK DOWN the rubber sunroof seal. There IS a SPECIFIC product for that available at auto parts stores ( can't think of name right now ( sorry))..ANYWHO...have 2 power sunroofs 100.00 each...NO SHIPPING .....ONLY available at TRUCK-INS ( UPON REQUEST) Gotta get yer own switch ( not rocket science...& VERY attainable)

Thanks! Nope, this one opens (electric) all the way, to the outside. Can be stopped at any position. Also has the vent feature.

And except for power (electricity), nothing is needed. All built in, ready to go.

I have Limo roof in both of my G30's and the only time they leak is when a leaf gets in between the glass and rubber seal....10 yrs now no leaks on either, as far as the seal to the van...

Looks great! I wouldnt mind having one of those for my vans.

have 2 webasto units 33 X 20 is what they call them has switches and complete ( for remote switch location) 100.00 each (used...replaced under warranty by Explorer Vans for leak) no leak found at sunroof glass seal, only at the roof to frame seal. when the complete roof is apart they always replace the sunroof b( as its all apart anyway)

Interesting story-I really wanted to see if any of the glass shops could restore the current Le Van sunroofs. The first three i went to said no and directed me to someone else who might be able to help. Needless to say i was getting disappointed but upon the last one (South Tacoma Auto Glass), the owner stopped everything and walked out to my van.

He was really excited at the Le Van sunroof because back in the day, he was the main dealer for those specific models. He took me back into his shop and he had two of the three seals i needed and gave me written instructions on how to replace these. He went on to explain that Le Van sold its company twice and now is exist under another name but the products are available.

Needless to say, i was pumped that i didn't just buy one and settle for something that i wasn't really going to like.

that's good news
