The Thor Sanctuary 19P is a compact, off-grid-ready Class B diesel motorhome built on the heavy-duty Mercedes-Benz Sprinter 2500 chassis.

Key Specifications & Dimensions
• Overall Length: 19 feet, 8 inches (to 19' 9"), making it highly maneuverable and easy to park compared to larger RVs.
• Chassis & Powertrain: Powered by a Mercedes-Benz turbo-diesel engine paired with 4x4 / AWD capability and lifted off-road tires for backcountry terrain.
• Weight Capacities: Gross Vehicle Weight Rating (GVWR) of 9,050 lbs and a trailer hitch rated for 5,000 lbs of towing capacity.
• Tank Capacities: Roughly 19–25 gallons of fresh water, 20–26 gallons of gray water, and a 4.75-gallon cassette toilet system for black water.

Interior Layout & Living Features
• The 19P Floor Plan: Unlike the fixed-bed 19L layout, the 19P layout maximizes daytime seating. It features a power fold-out rear sofa bench equipped with three seatbelts. At night, this electronic sofa folds flat into a spacious 73" x 70" sleeping area for two adults.
• Center Kitchen: Outfitted with a 12V single-door refrigerator (accessible from both inside and outside the van on newer iterations), a microwave, a sink, and a portable cooktop that can be moved outdoors.
• Mid-Ship Wet Bath: A fully enclosed private wet bath containing a shower, a sink, and a cassette toilet, eliminating the need for traditional black tank sewage dumping.
• Cockpit Luxury: Features premium Mercedes-Benz safety engineering, typically including swivel captain's chairs, adaptive cruise control, lane-keeping assist, and a digital touchscreen infotainment dash.

Off-Grid Systems & Power
• Reliable Power Setup: Commonly built with an advanced electrical backbone featuring a 3,000-watt power inverter paired with high-capacity house batteries (either dual AGM or upgraded 400Ah–460Ah lithium battery banks).
• Solar Charging: Includes 190W–200W rooftop solar panels connected to a charge controller to maintain power while camping off the grid.
• Climate Control: Uses a premium, single-appliance Truma Combi system that serves efficiently as both the diesel furnace and the instant water heater, alongside a roof-mounted 11,000 BTU air conditioner.
