I thought I would post a few pictures of my project. Hope that's okay with the OP.
The Onan 3600 LP installed in the front compartment. A bit of a tight fit but enough room for my 2 - 6 volt GC batteries next to it.

My 50 amp automatic transfer switch along with a 1000 w pure sine wave inverter are mounted on the wall separating the front compartment and the pass through storage.

The remote start switch is mounted in the trailer just above the fuse panel.

Anyways, I wanted to report some financial considerations as well. In my case my trailer did not have an optional "generator prep" option so I don't know how much that cost would have been and therefore how much I would have saved on installation as a result but I did get 3 estimates from my dealer and 2 independent RV repair shops for this work. My quotes ranged from $8,000 to $9,000. I purchased my generator and ancillary parts (transfer switch, remote start, harness, etc) from an online store for $3,700. I paid a mobile certified RV repairman $2,200 for installation including all miscellaneous wiring, boxes, switches, etc. So, overall I came in at $5,900.
