Welcome to the forum!
It's a rare model and probably not many here have direct experience with it. But as with any rv purchase, if the size and layout suit you, then proceed with checking out the vehicle and coach portions. It's like buying a car and house in one. If you are new to rvs, by all means have a qualified mechanic and rv tech check it out.
I'm certainly not implying you should rush to buy it, but in today's seller's market, you should rush to check it out since it may not be for sale very long. Then you can rule-it-out or rule-it-in fairly quickly. Then offer a bit less for it, especially if issues are found (and there are almost always issues). Some are deal breakers, some are par for the course and can be considered in the selling price or your offer.
It took us over a year to find the perfect rv for us. Good luck.
