Agree...almost half of the hours were for the structural deck repair. So to be fair the roof probably took about 30 hours which was mostly by myself, 1 day out of those 6 days I had my son help for 6 hours.
I must make a summary judgement here about the factory design and construction. As a qualifier, I'm a Construction Manager and GC for my entire career so you can get where this might go. ;)
In buildings, the design industry has evolved to make "system" redundancy a standard requirement. Like a Wall "system" will have more than one layer keeping the bad stuff out (water/organisms/etc) and the good stuff in (Conditioned air/heat). When you see a brick wall on a building, it was designed and built to have more than one waterproofing layer before the water would find its way into the building. Behind the brick is an air gap/cavity which then has a membrane against the back of another inside wall assembly (block or framing). The air gap relies on gravity and open venting to allow any water that gets through the first barrier (brick) to fall and exit the cavity through a "weep" hole before it makes contact and damages anything inside. So when I assess a building system or assembly failure for an owner, and the failure evidence can be seen inside the building, then we know multiple layers of protection have failed.
In this particular trailer, there is no design of redundant systems or layers, once there is a breach of the first layer by water (EPDM or Exterior skin) the damage is nearly always certain. It makes me want to design and build the camper out of non soluable materials, thats why I replaced the top deck Luan with FRP. One silly pinhole in the EPDM glued to Luan becomes a huge mess. The aluminum frame is safe from water damage but any other wood based materials are not. So Camper repair for a water breach becomes a catch it and kill it urgency.
