Replacing Driver's side glass on 390QS

Chester Hill · 02-05-2019, 02:28 PM

Have a 2011 Berkshire 390 QS with a stationary window with seal failure on the driver's side. You can hardly see out of it to look at the outside rearview mirror. It looks like a few screws on the interior track on the bottom must come out & then probably a small retainer piece that holds the glass in the track. Has anyone changed this glass before? Where have you gotten a replacement? It has an odd angle and a radius edge in one area. Not a typical looking square piece of glass. It needs to be tempered; but should I get it insulated again or single and install a spacer to make up the thickness difference? Also will have to deal with the same issue in the future with the entrance door glass failing also.

Have the same window fogging up. Lookslike like a real PIA to remove. Will be interested in how it comes out. Skip

Have not messed with the windows (yet). If this were my problem I would reach out to Forest River PARTS. I suspect they will charge an arm and a leg IF they return your call.

I would also try to figure out who in Elkhart makes the windows and make some calls.... a quick Google reveals these people... May not be the ones you want, but it's along the lines of what you're looking for.

Cleer Vision --Home

Also, glass businesses (not RV style) do make to order multi pane windows...

So that's the start of the path to the part.

I would NOT go to a single pane. There is too much surface in the cockpit already, with the accompanying heat gain/loss for me to further degrade the R-factor up there. Plus, getting it to fit would be as much work as finding the right part.

The entrance door is made by a separate company and bought by FR as a complete unit with frame etc. The name of the company eludes me right now, but I suspect it's on this forum somewhere. Again, maybe FR will tell you.... Once you find the door maker you have the window. Look on the door/frame there MAY be a sticker or engraving on there somewhere.

If fogging is the issue there are folks who specialize in repairing fogged, discolored or damaged RV and trailer dual pane windows. I've seen ads in some of the RV magazines. I used a firm in Collyville Texas to de-fog the two front driver & passenger side windows on my old Newmar gasser several years ago. They did a fine job. Don't recall the price but I know it was a lot cheaper then replacing. You can send them a picture with measurement and get an estimate. Had to leave the rig. They disassemble and repair. You might not be near Texas but its a start. rvfogpros.com
Good luck!

Ah yes, hadn't thought of that. Matter of finding the leak, filling with Argon and sealing.....

Oaklevel · 02-06-2019, 06:24 AM

I would take it to a glass shop.

Eagle5 · 02-13-2019, 05:33 AM

Did you get it fixed?

I wanted to chime in because I have a brand new 2019 and my drivers window fogs up when it rains. RV is stationary at campsite. Rained, and the only window to fog up is the big driver window.

And by the way, mine is single pane. Thought that was kind of weird. 2019 34qs

Am waiting for the spring to come, then I will remove the glass and send it out to be re-made. I have a friend who works for a window company who told me he could have a duplicate made & tempered in 2 weeks or so.

Replaced mine in 2013 for the same problem. Had to remove the cabinets to get to the upper mounting screws. Took about 1 1/2 hrs. Got the window from FR, cost about $800 back then.

As someone said there are companies that will reseal & re-gas the window but I don't know the cost.

If you go the replacement route, remember FR isn't the only company that uses that window. Shop around.

And FR will NOT be the cheapest.

Ceedog,

Thanks for the reply! The small screws on the bottom track need to be removed? And those screws hold a small strip, a window stop? And then that is the same on the top of that window also? This is the stationary unit that you have to look out to see the rear view mirror on the driver's side.

Thanks,

Rick

ceedog · 02-26-2019, 11:55 AM

CH,

You're gonna have to remove all of the screws around the perimeter of the window.

Make sure you have someone on the outside to hold the window. The silicone seal may have loosened.

NO3putt · 02-26-2019, 03:03 PM

In our 390 QS in order to reach all the screws around window frame, over head cabinets,and part of dash near driver needs to be removed. What a PIA this will be. Skip

Chester Hill · 03-09-2019, 12:32 PM

Did you have to remove the entire frame with the 3 pieces of glass, the dead lite window above the 2 lower pieces, the sliding piece, and the front stationary piece, to change a single piece? Did you change the piece you look through from the driver's eat to see the outside rear view mirror? Could you give me a little direction on how you did it?

Thanks

Driver's window is single pane due to safety reasons in case of an accident.

ours is duel pane window, other wise it would not be fogged up. Just wish we could easily pull it out to get fixed. Skip

I had my 2008 390QS done about 6 months ago. Looks like a bb gun hit it the man said. A company out of Greensboro, NC, RVG RV Glass Repair Services did it. He had to get the window made and he said it was not a fun job. They do Fog windows and are get. They have a place to plug in your MH ask well Number 800-632-4941or www.rvglassrepairservices.com hope this helps.

I realize this thread is several years old but hoping some of the original posters are still active on the Forum.

I have a 2010 390 QS having this same window replaced at RV Glass Repair in Greensboro and they're having trouble getting the window out. The 2010 390QS has a cabinet over the upper portion of that window as well as the left side of the dash that is obscuring some of the window screws. Did they have to remove the cabinet and dash on your 2008 to replace the Window? They are hesitant to remove the dash for fear of the electronics in that side dash unit (Equalizer leveler controls and transmission selector). They can't go any further until they get some "help" but I don't know who or what that help needs to be. Any info you may have on your repair would be appreciated.

@bikerscol I have a 2008 360QS and had my driver's window removed, fixed, and installed and they did not take apart the dash. However they did fully remove the cabinets above the window.

I dont know if your RV and mine are designed the same at the driver's seat but I assume they are. I hope this helps.
