After two years in drydock we set sail for a relatively short trip to Old Orchard Beach, ME. I decided that taking secondary roads was the way to go on our maiden voyage. That proved to be my undoing. I grossly overestimated my RV piloting skills and put the rear wheels over an unseen curb on a backroad 14 miles into the trip. All I heard was a bang and suddenly I was covered I glass chips. I have a Xmas tree shaped set of cracks on the driver's side window about. Five inches from the end of the wndow and arc shaped crack in the same vicinity on the passenger side. I guess it was enough to twist things enough to crack the windows. Does this seem right?
I'm stillonvacation and have't done much research on new windshields yet.both cracks are outside the wiper arc and I can still drive it fine. Does anyone have a suggestion for replacement?

Mike...

So sorry to hear of you plite regarding the front windows...
seems like an odd thing to happen... maby the wind screens did not have as much clearence around the outer frame as they need in order to "flex". Not the typical thing.
I suggest you all Jim Bounds in Florida for his opinion on wind screens for our coaches,the guy is a great help ( as is Jimmy K.)
Hope you have good auto glass ins.

Dan who will be getting both replaced this winter Borlase

Sorry to hear your news, but I've also noticed that these GMC's are
deceptively easy to drive. I keep having to remind myself that this
isn't just a big Cadillac. I managed to lightly touch an awning arm on
a narrow construction zone approach to the Golden Gate Bridge. I
thought for sure it was much worse but it was luckily only a loud
wake-up call.

It was a reminder that these are still motorhomes, no matter how well
they drive.

Good luck with the new glass. At least you can restart the clock on the
clouding issue some have. Jim and Jim seem to be good sources (I think
I've seen stock lying around at Applied when I was there.)

My PO made it sound like this glass may not be quite as exotic as it
sounds. Maybe not in stock everywhere, but available somewhere. No
telling what the quality will be, though.

Sounds about right. Some folks have cracked thier windshields by jacking the coach up improperly. Check with your insurance company, they may cover the new glass. I've heard that foreign made windshields have issues with fit. The only american made ones are Viracon, which I had put into my coach 5 yrs ago.

Regarding the windshields I suggest that you make arrangements with a glass installer you trust and have him get the Viracon glass through Jim Bounds. That way your supplier can, and should, talk with Jim to get his special, learned from experience, tips on installing the windshields.

Regarding driving. There is a natural tendency to drive the coach too close to the shoulder. For me, at least, I am still regularly checking my RH mirror to check that I'm not drifting to the right.

Mike,
You need to give the frame a very thorough inspection. Frame
flexibility could be an indicator of rust through. I've never heard
of this happening whle driving. This sometimes occurs when jacking
the coach from one of the front corners.
When ours broke, I called Jim B and he had his glass man drop ship
new glass, gasket, and lock strip to a glass replacement outfit that
Jim's guy had done business with in the past. RV windows are almost
standard in many applications, just shaped differently.

Mike

If you can get someone to provide you with the 'wag??' numbers, any glass
company should be able to get new glass and give you an opinion on the
condition of your seals.
Specify the 'better' brand of glass.
This should be an insurance claim.

If I could get mine replaced where I live, you shouldn't have a problem
where you are.

Libby, Owens, Ford has a glass manufacturing plant in Salem Industrial Park.
U.S. Plant still making OEM replacement windshields etc. Some kind of
throwback to an earlier era I suppose. They work through companies like
Applied GMC and drop ship to a local Glass Wholesaler. Couple of days
service. Marked LOF in the glass. The Chinese don't own Ford yet.

Mike,
The glass number is etched or decal in the corner of the glass.
Right and left side numbers are different. Any good Auto Glass
co. should be able to order replacement glass using these numbers.
It took 3 days for my replacement glass to arrive in Ft. Worth TX.
You may need a new seal. Sometimes you do and sometimes you don't
Again you glass installer should be able to check this out. As already
mentioned new seals are available from Coop Motors (Jim Bounds).
I don't know shipping time on that. Give Jim a call. He can answer
any and all questions.

I grossly overestimated my RV piloting skills and put the rear wheels over an unseen curb on a backroad 14 miles into the trip. All I heard was a bang and suddenly I was covered I glass chips. I have a Xmas tree shaped set of cracks on the driver's side window about. Five inches from the end of the wndow and arc shaped crack in the same vicinity on the passenger side. I guess it was enough to twist things enough to crack the windows.

On the Titanic, the passengers went out on deck and were putting the ice shards into their drinks, no such luck here...

I am not surprised to hear the result. We have been warned REPEATEDLY not to use the jack on the front bumper to jack up the RV and change the front tire. It has been know to flex the coach and since the rubber around the windows has taken a sort of set and is not as flexy as it used to be, would crack the windshield..

This is probably what happened to you.

I think there is someone near Indiana that can service glass as can Jim Bounds and I believe, well all the providers should be able to help you, Jim K and Miguel. I see these guys on the GMCnet off and on. There are a couple others too, I don't recall who they are.

Sorry to hear of your adventure with the IceBerg but glad you guys are safe. Your problem had an extreme result and shows how these old girls get stiff in their older age.


Hope one of the providers can help you.

We talked about this several years ago and I still find myself doing just that even after 15 driving my GMC. I have never had that problem with any other vehicle including large trucks!!

I've always been curious about that flex. Before joining the net, I routinely would jack on one side or the other and my GMC co-horts did the same with no problems. I'm wondering if part of the issue may be the size of the glass itself and how close or tight it may be in the opening.

Same here Bob. My frame is/was so rigid jacking from one side in the
front would always raise both sides and I've never cracked glass doing
it. I had the coach up on huge, tall jackstands to swap out the
engine and I noticed after the thing had been up a week, that one jack
stand had a quarter inch between it and the frame.

Methinks you haven't ridden in the passenger seat enough! Riding there,
you're sure the driver is going to plant every mailbox right between your
legs. After enough riding there a while, I'm happy to drive well to the

Remember that the rear track is wider than the front and keep that in mind to prevent more curb rash.

I've jacked my GMC all kinds of different ways and had no issues with the windshield before this.
I must say that I hit the curb very hard at speed and that must have tweaked the body considerably to break the windshield like it did. I had all kinds of stuff flying off shelves and out of the fridge.
Looking at the glass it seems like the curved window was trying to be flattened out (to > 90 degrees) kind of like what happens to the corner of an open shoe box if you tried to "rack" the sides back and forth. Glass doesn't like that treatment apparently.

I paid a lot of attention driving home as to why I might have made this mistake and I think it's because I use minor road imperfections to mentally map where the wheels are on the road. I can "feel" the front wheels quite well but I cannot feel the rears at all. Since the rears are wider I hit things.
I adopted a sight-line technique whereby I keep the centerline intersecting the left corner of the dash and the white line at the edge of the road intersecting where the windshield divider hits the dash (or maybe just a little to the left of that). I had my SO in a car behind me to verify I was where I thought I was on the road.

I tagged the walkway on a narrow bridge 5 miles after buying my GMC. It
takes a while to get used to the width of these things.

I got comfortable with it pretty quickly but on really narrow roads it's
still kinda "iffy" as to where those right rear wheels are running. I
have stuck a "sighting device" to the inside of the Driver's side
windshield. A piece of black electrical tape about 1-12" long. When I
really need to place the coach on the road accurately I put that piece
of tape between my eyeballs and the centerline of the road. Driven some
pretty narrow stuff with that sight keeping me centered.

Oh... and I ended up covering about half of the tape with Gray
electrical tape which shows up much better at dusk or at night. A
two-toned sighting device!

I should sell these...

After making it home to California from Ohio I was driving through a parking lot and sideswiped an old Cutlas Calais. The left front fender had been damaged and when my door hinge caught it I nearly pulled the whole fender off!

My door now closes with more difficulty than before.

It's a tough lesson to learn.
