Thinking about the roof.
Mine is now permanently oil canned due to a previous, confirmed impact of some sort. I'd prefer to not replace, all things considered, but will if necessary.
Regardless if it replaces, or not, thinking there's a better way to support the roof panel and increase headroom, but seeing what y'all think.
Add 3 additional cross supports, thinking a heavier rolled hat channel, then seam sealing directly to the bottom of the roof panel, removing the support that runs the length, completely.
Now, I realize why they're meant to move, but they did attach the hood support in a similar fashion, it's more visible than the roof.
If I have to replace or even remove the roof skin, half inclined to find a shop that could roll ribs into it. Know it's possible on smaller flats, but unsure how it could be done on larger, curved metal, but where there's a will there's a way.
Even thought of putting the external ribs, like what is on most with luggage racks, simply as structural component, but thinking that would look hideous.
Part of my thought process is also providing support for a "xx" ga sheet metal headliner, one that could be scrapdaddied, as a finished product. If rust can be abated, I see no reason that access would ever again be necessary, even if that meant surface mounting interior domes. Could always pull wire back through, if an event dictated.
By triple coating the bottom of the roof skin, again, in scrapdaddy fashion, possibly even blanket insulation glued to the underside of the coated roof skin, then a sheet metal headliner triple coated, I "think" that'd minimize the tin can affect plus it'd be durable.
So, why would it be a bad idea to raise the roof supports to the bottom of the skin and attach with a seam sealer?
Why is a sheet metal headliner a bad idea?
Thought about weight, and why the gauge is listed as "xx", so for consideration:
22GA 1.25 lbs psf
24GA 1.00 lbs psf
26GA .75 lbs psf
Figuring coating to add .50 lbs per square foot, for one "layer", calculated from Ron's coverage and product.
Rough calculations put the total at 36sf.
So, while adding a minimum of 72lbs to the highest point on the Pig, impacting the COG negatively, going to be a big issue?
