    AI summary

    The 326SRX is the kind of floor plan that makes you forget you're not in a sticks-and-bricks. Solid surface countertops, hand-glazed hardwood cabinet doors, a deep oversized stainless kitchen basin, and a Cougar Platinum orthopedic mattress that owners consistently call out as a genuine upgrade over the competition. The fully enclosed and heated underbelly with enclosed dump valves makes cold-weather camping viable, while the Polar Package Plus zero-degree rating and 15,000 BTU ducted A/C keep things comfortable at both ends of the thermometer. XL pass-through storage is a practical highlight, and the 50-amp service comes pre-wired for a second air conditioner if you want more cooling muscle down the road. Keystone's reputation for solid frame durability and better-than-average resale value backs up what the feature list suggests. This is a well-rounded unit with real staying power.
