If anyone is curious, I'll save you the trouble of joining just to read the NFPA 1192 regs.
NFPA 1192: Standard on Recreational Vehicles
On page 1192-5 they basically state the regs apply to new construction recreational vehicles manufactured after Sept 2011. Since my truck is a 2001 and I'm not an RV manufacturer, and considering the regs aren't retroactive, I rather suspect they simply wouldn't apply (presuming they apply in my county/state in the first place). Anyway, for $47 you can buy the PDF, which you can print, or for $39 you may buy their printed copy, or you may simply read it online for free. Here's the table of contents.

Anyway, using these regs as guidelines as I make modifications over time may save me trouble down the road, which I think was your intent. It's obvious someone put a lot of thought into these so I thank you for sharing the information.
Unfortunately, this is exactly how government grows. Worse, it puts a bureaucrat in a position to interfere with your private property rights. I'm saddened these things aren't offered as best practice guidelines for citizens to use as they see fit. E.g. use them, don't use them, it's up to you but you're gonna get sued anyway, so why interject the bureaucrats?
We don't need more government regulations!
Cheers,
