Horizon 20 Inch RD Special Marshal Review

Horizon 20 Inch RD Special

Horizon manufactures excellent, tight, well-built, heavyweight, heavy duty, horizontal offset firebox cookers that carry a lifetime guarantee against burnout! They are constructed from all new, high grade steel and cooking chambers are built from 1/4″ thick structural pipe to tight tolerances. Remember, heavy steel holds heat longer, distributes heat more evenly, cooks better, and uses less fuel. But Horizon smokers go beyond heavy metal. They are a culmination of design and manufacturing ideas gleaned from decades of cooking, cutting and welding. Even so, any offset design intrinsically causes the cooking chamber to get hotter near the firebox and cooler on the other side. So Horizon makes a clever “sliding convection plate” (below right). It is a heavy steel plate which deflects heat and smoke downward and disperses it more evenly through the chamber.

Horizon sliding convection plate.

Horizon owner, Roger Davidson, feels the larger his BBQ smokers get, the better the heat spreads from side to side and front to back. For this reason he steers people away from their 16″ pits. His RD Special features a 20″ diameter and a few nice extras:

– Counterweight for the heavy hood for easier lifting

– Oversize 20 inch Wagon Wheels

– And their Sliding Convection Plate

These convection plates are Horizon’s most popular accessory. They are offered as an option for most factory direct orders and can be retrofitted onto all Horizon 16 and 20 inch smokers and some 20 inch Oklahoma Joe Longhorns. They can also customize these plates for many other offsets. Call 866-468-4066 for more information on additional sizes and prices. You might even get to talk to Davidson.

Horizons have framed cooking grates made of 9 gauge expanded metal welded to square tubing. The expanded metal is flattened with rollers to create a smooth surface. Horizon claims each individual rack will support over 100 pounds. All models come with chrome spiral handles that are cool to the touch. Built in heat indicators, a lower storage rack for charcoal and wood, hinged firebox door for removing ash, and an ash rake are also included.

No assembly is required on current models whether purchased direct or through a dealer.

Masterbuilt MPS 340/G ThermoTemp XL Propane Smoker


This is the first propane smoker with a thermostat, making this baby foolproof. Set ThermoTemp’s dial from 175° to 350°F and the thermostat inside will adjust the burner just like an indoor kitchen oven. All you need to do is add wood to the tray above the burner to start smokin’.

Our Favorite Backyard Smoker

The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing. At its crux is a patented firebox that burns logs above the cooking chamber and sucks heat and extremely clean blue smoke into the thermostat controlled oven. It is our favorite smoker, period.

Is This Superb Charcoal Grill A Kamado Killer?


The PK-360, with 360 square inches of cooking space, this rust free, cast aluminum charcoal grill is durable and easy to use. Four-way venting means it’s easy to set up for two zone cooking with more control than single vent Kamado grills. It is beautifully designed, completely portable, and much easier to set up for 2-zone cooking than any round kamado.

Grilla Pellet Smoker proves good things come in small packages

We always liked Grilla. The small 31.5″ x 29.5″ footprint makes it ideal for use where BBQ space is limited, as on a condo patio.

The Cool Kettle With The Hinged Hood We Always Wanted


Napoleon’s 22″ Pro Cart Charcoal Kettle Grill puts a few spins on the familiar kettle design. In fact, the hinged lid with a handle on the front, spins in a rotary motion 180 degrees. It’s hard to beat a Weber kettle, but Napoleon holds its own and adds some unique features to make the 22″ Pro Cart a viable alternative.

Blackstone Rangetop Combo: Griddle And Deep Fryer In One


The flat top does the burgers and the fryer does the fries. Use the griddle for bacon, eggs, grilled cheese, and so much more. And why deep fry indoors when you can avoid the smell and mess by doing it outside!

The Good-One Is A Superb Grill And A Superb Smoker All In One


The Good-One Open Range is dramatically different from a traditional offset smoker. By placing the heat source behind and under the smokebox instead of off to the side, Open Range produces even temperature from left to right, something almost impossible to achieve with a standard barrel shaped offset.
