The difference that matters

Full-time fifth wheels of about 41 feet, separated by mass and systems. The Jayco Pinnacle 38SSWS weighs 15,625 lb dry with a 3,370 lb pin and an 18,700 lb GVWR. The Brinkley Model R 3710 weighs 18,750 lb dry with a 3,450 lb pin and is rated at 23,500, giving 4,750 lb of cargo capacity against the Pinnacle's 3,075.

The Brinkley's systems are built for living off the grid: a 200Ah self-heating lithium battery, a 3,000 W Victron inverter with DC-DC charging, 400 W of solar, a frame-mounted two-zone climate system in place of roof air, MORryde independent suspension with hydraulic disc brakes, a 290 cu ft heated basement, an outdoor kitchen and a dishwasher. Its rear entry door keeps the bedroom, bath and fridge usable with the slides in. The Pinnacle brings a zero-degree Climate Shield package, a 40,000 BTU furnace, six-point hydraulic leveling, a 21 cu ft residential refrigerator and a 72 by 80 inch king mattress.

The Pinnacle is the lighter tow and the easier match for a heavy-duty pickup. The Brinkley suits full-timers with the truck to match.

Jayco Pinnacle 38SSWS: Full-timers who want a residential king bed and four-season build in the lighter of the two.
Brinkley Model R 3710: Full-timers with a big truck who want lithium, a large inverter and independent suspension standard.
