I have had three 5 ers with generators
I needed to install a new one for my Redwood Sequoya.
I bought a Onan 5500 from Norwall and.
I paid less for it than I would have paid for all these portable that you have to double up with to have enough power.
You rig should already be wired to fit the Onan.
Plus you can start it from inside the trailer.
Make sure you get one with the 20 amp circuits.
You will thank me when you start it from inside when it is pouring rain outside.
If you like, I can look up the part number for the one I bought.
Shipping was free when I bought mine.
I t is the generator that the rig came with, and the install is pretty easy.
Let me know if I can be more helpful
