Seems to me like the hardest part is to fish the new wires. From what I can tell, they didn't provide any conduits to fish wires through. Just bundles of wires tie wrapped to frame members. Any additional circuits would require disassembly of the ceiling panles or runs under the floor of the unit. Please correct me if I'm wrong.
Anyone know where the transfer switches are on a 92 36' LY?
Unfortunately, you don't just 'add a few circuits' and 'beef up the transfer switch'. To
do it right (which is the ONLY WAY), you need to
replace the 30
amp transfer switch with a 50 amp version, replace your 30
amp 10/3AWG shore cord with a 50 amp 6/4 AWG unit, replace your 30
amp single line circuit breaker box with a 50 amp dual line breaker box and then add the extra circuits (like your #2 roof A/C) and split and balance the circuits so the load is even across both incoming legs in the breaker box.
Sounds simple, doesn't it?
Then you need to
be sure that your generator has the capability to
be re-wired for dual 120VAC circuits and run the 6/4 AWG wire from the genny to
the new transfer switch.
Still with me?
If you're not completely familiar
with 120VAC and 240VAC wiring, this is NOT a DIY job.

So the short answer is it can be done with the right knowledge. Or you can take a chance on being a pile of ashes....
