Our 16TBS is 10 years old and I would not hesitate to buy another used one. I suggest continuing the search for one with the aluminum roof, but that's just because I don't know anything about longevity of the TPO roof.
One important thing to keep in mind appliances and equipment will also be as old as the camper and RV appliances don't last forever, unlike the camper itself. You may eventually need to replace things like an awning or hot water heater, or exterior lights, but that's true for any brand RV. And unless the previous owner was really diligent, budget for new tires and wheel bearing service.
