I finely discovered what happened this spring when I was able to get up there and begin repair assessments.
The previous owner had a serious roof leak, and instead of replacing the whole roof, decided to rip out the front fifteen feet of rubber and ply, and replace it with luan, and then paint it with white roof coating. So when the caulking failed on the eight foot wide joint, it peeled away on the interstate and left me with this.
I can't believe what he had done, but am now stuck with it to fix.
We bought it knowing it had water damage issues, but did not know the extent until now.
The rest of the vehicle is as near perfect as I could expect for the year though, brakes, engine and tranny are all tight and trouble free, so I feel it's worth the time and effort.
And all the appliances work as they should with the one exception of the temp cut off relay on the hot water heater.
I counted the cost of total rebuild and decided against it in the traditional sense.
Having found ( blessedly ) aluminum framing, I am going to replace the roof this year, and next season begin rebuilding it from the inside out, with the siding possibly done last.
This is a backwards way of doing it but will accomplish two objectives.
first it will be easier labor and time wise, as well as stretching the dollar cost out over a longer period.
Second, ( and most important to us ) it will allow us to actually use it as a functional camper without a year or two of down time.
We have both decided that this is not our last RV.
I am hoping though, that the next one might be. We both have a fondness for class A's but appreciate the ease and cheaper cost of repairing class C's.
As I am having severe computer problems, I don't know how faithfully I can post pics of the progress, but will try.( if it ever stops raining here!)
