Default 2005 Onan Marquis Gold 5500

Have access to one of these that was removed from a toy hauler that had a tree fall on it (not on the genny, though). Says it was running at the time.

I figured out from the serial number that it was made in 2005. Not able to decipher the model number using the info in the sticky.

Model: 5.5HGJAB-1038D

It is a gasoline model. Trying to assess whether this is worth getting running and convert to propane for use in a fifth wheel. To the good, there is a box of extras that includes a new carb in a plastic bag.

What would be the steps to perform before trying to start it to see if it will run, assuming that it sat a couple of years?

Might want to clean genhead slip rings before making AC. (they oxidize if they sit)

Haven't heard it on these yet , but the older model Marquis design ( BGM/NHM , horzontal shaft design) had a problem with the $245 AC voltage regs dieing if gen sat for months without cleaning slip rings
