Sorry that I can't be of more assistance. Knowing how cheap they go when they build these things, the wiring from the generator and the shore power connection to the transfer switch won't be any longer than absolutely necessary.
It will also be located in a water resistant enclosure and if you have a 120 volt 30 amp service like the brochure says, the transfer switch will have orange romex running from the shore power outlet and the power distribution panel to the transfer switch. I would wager that the flexible liquid tight conduit running from the generator isn't any longer than absolutely necessary because if its and its fittings cost.
What you need to do is open the access panel underneath the power distribution panel and see if there is an orange romex. if so see if you can determine which direction it goes and continue to follow it, eventually it will lead you to the transfer switch. If isn't orange figure out what color it is and follow that romex.
If you prefer you can start at the shore power connection and work your way towards the transfer switch from there.
FYI, I spent almost three hours this morning attempting to trace what I thought was the "C" channel speaker wiring. At the back of the Jensen JMW6A the "C" channel left speaker output was connected to a green/white lamp style cord. Others had told me that the "C" channel was connected to a sub woofer that was located under the clothes closet so I started looking there. Well I never did find the subwoofer nor the the green/white channel "C" wire.
What I did find was a green/white wire under the close closet, but it ran from the driver side outside light to the 12 volt power panel via the bed box out, the transfer switch compartment, a floor joist cavity, under the bathroom sink, up the wall alongside the fridge, and finally connected to the power panel wiring.
The orange #10 romex from the shore power outlet to the transfer switch ran into the cabin then exited the bottom of it, ran though liquid tight flexible conduit along the frame and then up into the transfer switch compartment where it exited the conduit and then the romex entered the transfer switch enclosure.
The orange #10 romex from the power distribution center ran over the fridge,down the wall alongside the fridge, under the bathroom sink where it entered the floor joist cavity, it exited the floor joist cavity in the transfer switch compartment and finally entered the transfer switch enclosure.
I still have no idea where that damn speaker wire goes and will not waste my time looking for it until I figure out how to remove the ceiling speaker covers without damaging them nor the soft ceiling.
I guess if you want to own a motorhome and don't have money to burn, you need to get your hands dirty and figure out where things are. The way these things are built. I am quite sure that mechanic at the RV service center has to do exactly what I did the first time they work on a new model.
