If I am following and reading this correctly, you have three layers of plywood plus the
rubber roofing. At what point does the weight on the roof becomes a consideration? (Besides
the RV tipping over). ??
All kidding aside, it does seem as if there is an exceptional amount of weight up there.
Keep up the good work. I enjoy what you have done and am looking forward to seeing the
end results.
Originally, the roof had 1/2" plywood covering the entire roof, plus a piece of fiberglass on top of that. Then of course, there was an air conditioner up there, (which I won't have).
There were also cabinets around most of the interior walls attached to the ceiling/roof, many of which I won't have due to the shelves on the walls in the kitchen area. That will reduce some weight at the top as well.
The plywood roof I have is 1/4" thick, plus 1/8" glued to the top of that. Now remember, todays plywood is NOT 1/4" nor 1/8", so it actually is probably closer to 5/16" than 3/8".
Yes, I will be adding another 1/8" (so to speak), down the center of the roof, as a 4' wide piece.
The plywood is actually about .106" or as they have it advertised as 2.7mm, instead of an actual .125" or 1/8". Clear as mud, right? Lol.
Back in the day when we bought 1/2 in or 3/4 in, that's what we got. We did not buy 3/4 nominal, with .710 actual. Drives me wild when looking at actual thicknesses. Not really, but it is annoying.
All in all, I think the weight up top will be just fine, and possibly even some less than what was there originally. I won't know for sure about the entire rig, until I get it on a scale, but I think it will be ok overall.
Glad you are enjoying the thread. Thanks for the post. :)
