I hope this helps.
FYI - You can only power 1/2 of the circuits in the power panel via the inverter. In other words, it will only power 1 leg of the 110v legs (there are two of them with 50 amp service) of the power distribution box. Therefore you can not power all outlets in the RV. This may or may not be a problem is you want to power the rear TV and the sattelite, and the audio equipment, if they are on different circuits.
You can work around it if you are good with power or order the RV to be wired accordingly.
