Has any one replaced the Fire Wall? If so, how difficult was it?

Been thinking about this question over night. I am trying to establish just what part of my coach would be “fire wall”. The engine lives in the living area. Not a usual situation for a vehicle or an aircraft where the firewall is, indeed, a FIRE wall. Hmmmm.....still pondering this one.

I agree, the GMC has a unique firewall, with a great portion of it made out of plywood.

In the automotive industry parlance, vehicles have not had a "fire wall" for decades before our coaches. It has been a engine bulkhead since the 40s. But, the term like that and dashboard still linger. (The dashboard, like in the curved dash Olds, was a leftover from horse drawn carriage and it was a piece that prevented the mud that the horse kick up from getting on the passengers.) What you have in front of you is an instrument panel.
As far as what is the "fire wall" in a TZE? I would have to say that there is none. While the plywood cockpit floor will resist burning for a while, there are so many breaches that it would not present a serious impediment to a fire. I think that this has been demonstrated a few times.
I don't no if you have noticed, but when there is a car fire that starts in the engine compartment, it will very quickly penetrate the engine bulkhead because there are so many places like HVAC ducts that can be burned through in short order.

The “fire wall” is the bulkhead between the driver and the engine
compartment. Still called that today in repairer lingo.
I admit that it gets muddy with the gmc due to the location of the engine.
That said, I assume he is speaking of the aluminum vertical wall from the
windshield to the floor plane. Which is why I asked why.

Tom, I'm so sorry to learn of your accident. I very much enjoyed meeting you and Oki at the Mansfield GMCMI. As I was parked next to you, I had to close my blinds on your side...so I wouldn't be constantly reminded and feel badly about how poorly my coach looked compared to yours! It was truly a beautiful coach.
I'm not on Facebook so I don't know the story - what happened?
If there's anybody I know that can "take two to make one" and do it right, it's you. You've got a ton of support here.
take care

Tom,
I have to ask because I am truly wondering.
Are you considering replacing the plywood cab floor or something else like the aluminum part of the cab??
I ask because there is a now single (widow) lady near me that completely gutted her coach. Part of what she did was to completely replace all the flooring, cab and all and it was all done from inside. I suspect that this may be part of an answer to your question.
