Up comes the old floor!

[Paladin]

I came home today and decided that I'd try to get the ramp up. Well, no joy, it broke my drill bit and pissed me off so I tried on the right front wood flooring.
I used my angle grinder and just dug in and cut the heads off anything that looked strong enough to hold the wood down. With some work and tons of smoke I got them all ground off. I wonder what I was thinking doing this with the door and front windows closed? I about suffocated myself and thought the neighbors would call the fire on me for lighting my bus on fire.
After some prying I got the wood up, it would have been easier with another guy helping plus I'm still recovering fro ma rotator cuff injury but it came up and then the grimy part.

It wasn't too bad really but this is only part of the bus too. I did find an old pair of glasses in there and some other stuff I couldn't identify without cleaning off all the hair and junk.

Ok, so now a basic course in hvac for this dummy. What are the different lines for? I know the fiberglass ones seem to be the output since they blow the bus full of junk if you turn on the fans but how does the rest of the system work? The tin tray coming from the smaller ones (yellow boxes) and then going over the air beam was rotted. Do I need to replace that and do I need those boxes?
I'm guessing that the rusty strip to the side of the fender is the air beam?
