Sorry I don't have the rating info. you are looking for, but it may be available on the Sundance website- you can download the owners manual, which should give you a ballpark. At the very least, just add in 50 amps in your demand load calc, and see where that gets you.
We have about twice your square footage, the Optima set at 60 amps, plus central air, and we are not even close to the 200 amps that we have service for.
However we do not have an electic dryer or range, but even if we did, we'd still be ok.
Many people with older electrical service, say 100 amps or under need to upgrade for a spa, but I don't know of anyone with 200 amp service who has to. Maybe if your entire home was electric- including heat.
