This will be of interest to those thinking of buying a new unit with all the latest technologies.
Now that some of these new ideas have had time to mature, they are proving not to be so great after all.
One example in particular is showing up now in the one-piece glued-in windshields, that are used in just about every vehicle application today.
The windshields are mounted, with appropriate adhesive, direct to the metal frame of the vehicle, car, truck, or motorhome. What could go wrong with that??????
Well, water will find its way to the lowest point it can travel, and then what? It enters at any point from the roof seam, mounted equipment, marker lights or the upper windshield that may not have been properly glued and sealed. (The upper windshield seal takes all the stress and generally fails in this area first.
) The water then will almost inevitably collect in the lower windshield glued area where it is trapped.
Over time, (not that long depending on climate)
, this metal mounting area will begin to rust, bubbling and expanding, and results in the huge one piece windshield cracking from the point of stress.
The problem/damage is not recognized by the owner until the windshield is removed and the problem is pointed out by the professionals who all too often are seeing this difficult to repair situation.
If you have a glued in windshield, do not allow any moisture to collect in this area and of course attend to any leaks immediately.
We owners of Airstream Class A units don't have to worry too much about the windshield cracking, as described above, as our windshields are mounted in rubber which is then mounted to the metal frame. However, if moisture is allowed to be trapped withing the rubber at the top and sides of our windshields, metal damage will be possible.
Keep your windshield rubbers sealed at the top and sides and be always on guard against water intrusion.
Just do a GOOGLE search for many examples, but this one applies to a 2007 Class A motorhome that has a glued in windshield in California.
