Oklahoma Joe’s Canyon Combo: two cookers sharing one frame
The Canyon Combo, model 24203004, puts a charcoal offset smoker and a three burner liquid propane grill side by side on a single wheeled chassis. The listing specifies 750 square inches of primary grate area, a further 281 square inches on the firebox grate, a 36,000 BTU rating for the gas section, assembled dimensions of 68.9 inches wide by 35.6 deep by 50.8 high, and a weight of 196 pounds. Amazon records a 4.2 star average across 18 ratings and ranks it fifth in the combination grill and smoker subcategory, which is a small category rather than a large field.
The design logic is straightforward and it is the reason this format exists. Charcoal with hardwood splits produces the smoke flavor that a gas burner cannot, and gas produces heat on demand without waiting for a chimney of coals to ash over. Owning both in one frame means a weeknight dinner runs on propane and a weekend brisket runs on charcoal, without buying and storing two separate cookers. Oklahoma Joe’s also promotes the sequence of smoking low and slow on the charcoal side and finishing with a reverse sear on the gas side, which is a genuine technique rather than marketing language.
The offset smoker side
The smoking chamber is horizontal with the firebox mounted on the side, which is the classic offset arrangement. Fuel burns in the firebox, and heat and smoke travel sideways through the cooking chamber to the smokestack, so the food never sits over the fire. Adjustable dampers on both the firebox and the stack are what regulate that flow, and learning to balance them is most of the skill in running an offset.
Two features address the parts of offset cooking that usually annoy owners. A removable ash pan on the side of the firebox means clearing ash without reaching into the chamber, and ash accumulation is the most common cause of a fire that starves partway through a long cook. The firebox also carries its own 281 square inch grate, which turns the fire chamber into a small direct grilling surface for wings or burgers while the main chamber runs low and slow.
Worth being clear about the running costs and the omissions. Hardwood splits and chunks are sold separately, charcoal is sold separately, and the 20 pound propane tank for the gas side is not included. An offset also demands attention: it is not a set and forget cooker, and anyone who wants to set a temperature and walk away should be looking at a pellet unit such as the recteq Flagship 1100, which holds a setpoint with a controller instead of with dampers.
Reading the cooking area figures carefully
The listing quotes 750 square inches of primary grate and 281 square inches on the firebox grate. It does not state clearly how the 750 divides between the smoking chamber and the gas grill, and those are two physically separate cooking surfaces that cannot be used as one continuous space. The capacity examples in the listing, two pork shoulders on the smoker or twelve burgers on the grates, are more useful than the raw total. Anyone sizing this against a single chamber cooker should compare usable surface per cooking mode, not the combined headline figure.
The gas side, and what 36,000 BTU means here
Three burners rated at 36,000 BTU combined is a mainstream figure for a mid size gas grill. BTU per hour is a fuel consumption rating rather than a performance rating, so it describes how much gas the burners can burn, not how hot the grates get. Heat retention, grate mass and lid design all matter as much. What 36,000 BTU across three burners does deliver reliably is the ability to set up two zone cooking, running the outer burners hot and leaving the middle one off for indirect heat, which is the most useful habit on any gas grill.
Build, mobility and the material fields
The chassis carries two large steel wagon wheels with rubber treads, pivoting cool touch handles on both the lid and the firebox, three tool hooks, a front shelf, a side shelf and a flat bottom shelf with a raised section for wood and fuel. Those additions matter on a cooker that has to be repositioned and that generates a lot of loose hardware and tools around it.
One material field does not add up. The listing records the outer material as stainless steel while also recording the color as black and the inner material as painted steel. A combination cooker at this weight and price is built primarily from painted steel with stainless used for selected components, and the photographs show a painted black body. Treat the stainless steel entry as a partial description rather than a claim about the whole cabinet, and expect painted steel to need the usual care: keep it covered, and treat surface rust early rather than after a winter outdoors.
At 196 pounds and 68.9 inches wide this needs real patio space and a two person assembly session. The warranty is two years on all parts.
How it compares
Against a dedicated charcoal smoker like the Char Broil Bullet 16 inch, the Canyon Combo trades compactness and simplicity for versatility and a much larger footprint. Against a portable propane unit like the Cuisinart Grillster it is not remotely comparable in mobility, and it is not meant to be. Against a Weber Performer charcoal grill it offers a true offset chamber that a kettle cannot match, at roughly twice the space commitment. The rest of this format sits under combination grill smokers, with dedicated units in smokers.
Who it suits
This is for a household with the yard space and the appetite for both cooking styles, that would otherwise buy two cookers and does not want to store two. It rewards someone willing to learn damper control on the offset side while keeping propane available for the nights nobody wants to tend a fire.
It is the wrong purchase for a small patio, an apartment balcony, anyone who only ever grills quickly, or anyone who wants smoked food without managing a fire. Those buyers should pick one discipline and buy a better single purpose cooker for the same outlay.
