Sounds like good advice. I still have a lot of room to put stuff under the camper seats in the back. I don't air down, so I can't justify installing a permanent compressor, but I bring along a 12v portable one when needed, mainly for my ATV or Tractor at camp.I can't tell you where the perfect place is for your inverter but I would not put it under the hood. Under driver's seat seems like a pretty solid idea. Not much else fits there. In my JLU mine (and OBA compressor and Noco lithium charger) are in the little hatch in the rear but you don't have that.
Personally I like air compressors outside. They are too noisy, still when outside, but I don't like them in the rig. Is there nowhere under the truck bed to mount your compressor?
Also, you mentioned cold camping/electric heater, etc. Do you not have room to stuff a CDH (Chinese diesel heater) somewhere? Super cheap and very effective.

I have plenty of room for a diesel heater in the camper. That's probably the way to go if I plan on cold weather camping. I still haven't figured out where to cut a hole for the exhaust though. So far, I haven't drilled a single hole in my truck.
