Camp Chef Mountaineer High Pressure Stove review

The Camp Chef Mountaineer is a two-burner propane tabletop stove built around a latching aluminum case and a refillable-cylinder hookup. The exact US product page identifies SKU MS40AX and lists two 20,000-BTU-per-hour burners, 40,000 BTU/hour total, 302 square inches of cooking area, a five-foot hose and regulator, matchless ignition, appliance-style controls and a three-sided windscreen. Those are manufacturer specifications, not results from a hands-on test. The page's 15-pound figure is not described as a minimum or packed weight, so it is not a meaningful backpacking-weight comparison.

A broad outdoor cooktop, not a compact canister kit

Closed, the Mountaineer looks like a sizable metal suitcase rather than a nested burner-and-pot kit. The manufacturer lists a 25-by-14.5-by-5.5-inch body, a carry handle and latch, and full aluminum construction. Its 302-square-inch cooking-area figure suggests a broad platform, but that area is not a maximum pan diameter. Camp Chef does not provide a numeric cookware limit on the cited page or in the exact manual. Measure the base, handle clearance and spacing of the cookware you actually plan to use; neither a large area figure nor two burner controls proves every pair of pots will fit.

For a stationary outdoor kitchen, a tailgate or a vehicle-supported campsite, the attractions are easy to understand: two independently controlled burner positions, a flat latching case, and the option of carrying a refillable propane cylinder. The exact product page includes a five-foot hose and regulator, while the tank remains a separate purchase. This is a different supply plan from a stove that screws directly onto a small threaded backpacking cartridge. The 15-pound listed value also belongs in context: it excludes the separate cylinder and has no manufacturer-stated minimum-versus-transport basis.

What the manual supports—and what it does not

The MS40AX instructions describe the controls moving from HIGH to LOW and call for a smaller low flame. That supports an adjustable-output plan for ordinary boiling and cooking; it does not establish precise low-flame stability, a measured simmer test, boil time or wind performance. The manual identifies a 40,000-BTU-per-hour output and warns that prolonged use with both burners on high may reduce output as frost builds at the tank connection. It advises low heat with griddles and warns against putting an empty vessel on a lit burner. These operating notes matter more than treating the headline output as a promise of faster cooking in every weather condition.

Three-sided wind panels fold out from the lid and attach with latches. They are part of the stove's documented configuration, not proof that adding a freestanding shield is safe. The exact manual describes the built-in panels but does not approve a separate windscreen; this assessment therefore leaves that finder field unknown. Do not add a shield unless current exact-model instructions explicitly permit it.

Setup is a real constraint

The MS40AX manual calls for LP propane and the supplied regulator/valve assembly, and names a Camp Chef MS40-6 hose and regulator. Its cylinder section specifies a roughly 20-pound-capacity tank with a Type 1 outlet, safety-relief valve, protective collar and overfill-prevention device. Before use, it instructs an outdoor soapy-water leak check. This is not permission to substitute another regulator, hose, fuel container or adapter.

The location rules are substantial: use only outdoors on a level, stable surface, not a plastic table; never operate under overhead construction; maintain at least 10 feet between the stove's sides, front and back and surrounding construction; and keep it at least 25 feet from flammable liquids. The manual also prohibits use in or on an RV or boat and says never to use the stove as a heater. Those requirements make the Mountaineer a poor fit for cramped shelters, enclosed cooking areas or a plan that depends on vehicle-mounted use. Read the complete instructions, use the supplied regulator, inspect the hose, and follow local cylinder and fire rules.

Who should consider it?

Consider the Mountaineer if you specifically want a two-burner propane cooktop for a properly spaced outdoor setup, appreciate its built-in panels and latching case, and accept carrying the separate compliant cylinder. It may be less suitable if your hard limit concerns stove-only minimum weight, a maximum cookware diameter, a separate approved windscreen, RV use, or very compact packing: the cited sources do not establish several of those requirements, and its manual explicitly rules out some use settings.

One model distinction is especially important when shopping used. Camp Chef's recall notice names older model MS40A, UPC 0-33246-21520-4, with specified regulator date codes; the exact current MS40AX page shows UPC 033246218014 and the recall page does not list that exact model/UPC. This is a narrow comparison with that notice, not a guarantee about future notices or replacement parts. Check the label on the actual stove and regulator rather than relying on the family name alone. Verify current package contents, seller, return terms and exact instructions before purchase; this assessment makes no claim about current stock or price.
