Cabover repair

[xtreemthrttl]

so! as a newbie to the rv world, i learned a valuable lesson when purchasing. pull the mattress off the cab over and look at the deck area!!!!
my girl and i have been prepping the rv for our maiden voyage this christmas season and though its come a long way quickly its not without setbacks.
she pulled the mattress out from above the cab only to discover the rotted wood from the notoriously leaking front windows! i knew it was only going to get worse and with the trip coming up, i needed to tackle this asap.

so as you will see from the pictures the damage and the repair. total cost, 1 weekend (approx 20hrs) and about 300.00 in materials.
i replaced the original materials with white frp panel for the exposed underside, 3/4 plywood for the main structure and white smooth hardboard for the inside finish. never done anything like this before, but it has to get done.
more pics to follow!

The issue is; unfortunately; far to common in class C's .

JMHO; The problem is mostly due to the cab and coach body being mounted independently and moving around at different rates , flexing and ruining the seam sealant.
Check all the seams frequently to protect your investment.

thanks skip!
i have learned a great deal about rv repair and signs of damage since all this started. im sure i have so much more to learn, but really just want to enjoy it!
i realize products have come a long way in recent years, but i wonder why i saw so much silicone around all the windows instead of a product that would seal better and last longer? i found a product called "osi quad max" comes in clear black or white. its not water based and unbelievably strong! reminds me a little of 5200 once its dry but more flexible.

i used it to seal up pretty much everything i could around the seams and caps for the entire front of the cab over area. i intend to do the rest of the rv with it also.
