Updated now, How to tell what A/C has for starting

So manual for a/C says RV products, I gather mine is an 8000 series in this 2004 fleetwood wilderness lite fifth wheel, model number is 8333B671 serial number is 120213337, so I gather that means mine has no hard start kit, and what make would this a/c be?
And would I be able to buy a hard start kit now to install, as I believe that makes it easier starting up, especially if I use a generator.
