It was EASY as pie once I figured out how the generator circuit was wired to the transfer switch and thru it.
Here is a link to my picasa gallery and you can see the pictures that I uploaded of the upgrades to our RV.

I ran the new wiring across the RV over the gray and black tanks then up thru the floor where the right side heater is (under the cabinets in the bathroom) I ran a snake down the wall from the original box and pulled the new huge wire up the wall. the rest of it was just connecting things up.
The biggest stumble was connecting the generator. I also have the onan 5500 with a 20 and 30 circuits. I wired the transfer switch with the 2 hot legs (SO.. when I am on shore power I have full power, when I am on generator.. one side of my panel gets 20a and the other gets 30a). works like a champ.
I think I spent less than $500 including the new 50a shore power cable.
If I can help let me know
