I gotta throw a bit in about header vs stock manifolds...
From my reading around the intar-webs about 440's, performance, and all that, headers are only going to help a guy out in a heavy RV in one place...wide open throttle and maximum RPM...where the stock manifolds start to lose flow. Seems like the 440 wants a bit of back-pressure to keep from detonating itself to death and keeping exhaust valve seats and exhaust valves themselves from burning up.
As far as talking to the guys at "O-Reilly's", well, hopefully you got lucky and are talking with somebody that knows something about something vs. the punks that only know small block Chevy's/Ford's (or worse, fart-can mufflers for late 90's Honda's) and such. As far as I know, there's only a couple of manufacturers out there that make headers to fit the Dodge RV/Van chassis types and still have clearance for everything.
Like I said, I switched my exhaust from 2" pipe (manifolds to Y-pipe) and 2-1/4" pipe (Y-pipe to outlet) over to 2-1/4" (manifolds to Y-pipe) and 3" from there, thru the muffler to the outlet, and added a 4-1/2" resonator tip. My exhaust sounds great IMO, cackles just enough to get my attention when I get on it full throttle, but just kinda blubs at idle.
I guess in short, if you can find them for a decent price (probably not, but ya never know) and if they fit (if those guys at O'Reilly's actually do any good), well, there ya go.
Otherwise, what is your generator rated at? Have you tried to load the heck out of it to help make sure it won't die on you down the highway? I've got a 5500watt (8500 surge) generator. I took 4 of those 1500watt heaters and turned them all on at the same time. Generator coughed for a split second and kept going. Roof A/C will probably pull something like, what, 2,000 watts on startup for a couple of seconds and level off at about 1,000 watts or so? And the TV maybe another 100 or so watts.
And BTW, I like the color of the woodwork. That deep brown wood behind the TV looks great.
