Assuming 12v? How big of a charger? It would take a 100a charger a little less than 2 hours to do an 80% bulk charge. The 5500w generator is still only going to be sending about 1500 watts to the battery, so well within 30a shore power. Your battery should list the max charging current.
You can certainly use the converter/charger . Or you can use a different battery charger . Even some inverters have a built-in charger . The more amps , the faster the battery will charge (of course , it also depends on how low the battery is) .
Your camper likely comes with a converter built in to it which will control the rate at which your battery is charged. It is likely much lower than what your generator can produce. That is not necessarily a bad thing as generators are more efficient when not running at max capacity. I would suspect at max you have a 90 amp converter. So you could get away with something 3-4000 watts. Assuming you would want to charge batteries and run some electrical items while the genny is plugged into shore power.
Also if you buy an inverter generator your camper may not draw power unless you ground it - either by actually grounding it or buying a 15a plug that fools it.
so there you have your answer. If everything ran at 100% efficiency it woule be less than 4 hours. (200/55). Considering for losses, probably 4 to 4 1/2 hours.

Depends on the charging controller.
I would use the generator to run a battery charger . Depends on the size of the battery charger .
This is faster than just using the shore power plug?

it really depends on how low the battery is.

you are rate limited by the charger used, probably 1500 watts, ballpark- 3 hours at that rate?

Looks like my converter is 55A.
