Monument Grills Mesa II 415BZ Review: Best Budget Gas Grill of 2026?

The Mesa II 415BZ gas grill from Monument Grills sits in one of the most competitive segments in backyard cooking.

On paper, grills in this price range look impressive. Stainless steel. Big BTU numbers. Large cooking areas. But none of that tells you how it actually cooks.

I assembled it, tested the heat zones, ran steaks across the Broil Zone, used the side burner, and evaluated the build quality honestly. Here’s the full breakdown.

Cooking Space Breakdown

• Primary Cooking Area: 405 sq. in.
• Warming Rack: 120 sq. in.
• Total Cooking Area: 525 sq. in.

The 405 square inches of primary cooking space is where you’ll do most of your work. The 120 square inch warming rack flips up when not in use, keeping the main cooking surface open and usable.

This size comfortably feeds 4–6 people depending on what you’re cooking.

Burners, Output & Heat Zones

• Four stainless steel main burners: 37,000 BTU total
• Side burner: 12,000 BTU
• Total rated output: 49,000 BTU

The two right-side burners function as the dedicated Broil Zone, and that’s where you get the hotter searing heat. The left side stays more moderate, which gives you real two-zone control.

If you’re cooking something like a Reverse Seared Steak, you can bring it up gently on the cooler side and finish it hard over the Broil Zone for crust.

This isn’t infrared marketing fluff. It’s simply concentrated heat where you need it.

Assembly & Setup Experience

Assembly took just over an hour. The packaging was organized, hardware was labeled clearly, and the instructions were easy to follow.

Compared to other grills in this price range, the build process felt streamlined and straightforward.

Mesa II Feature Updates

• Foldable side shelves for tighter patio spaces
• Flip-up warming rack that tucks out of the way
• Pegboard-style side panels for storage customization
• Two movable hooks included
• Porcelain-coated cast iron cooking grates
• Electronic push-button ignition
• Mechanical lid thermometer

The pegboard system is practical. It includes two movable hooks that can be positioned wherever it makes sense for your workflow. It keeps tools accessible without cluttering shelf space.

Side Burner Performance

The 12,000 BTU side burner isn’t decorative. It’s actually useful.

You can heat sauce while wings finish, keep butter warm for basting, or run a cast iron pan without adjusting your main grill temperature.

When making something like Grilled Chicken Wings, you can crisp them over direct heat while your sauce simmers separately — instead of constantly moving food around or running back inside.

Build Quality — The Honest Take

The steel isn’t ultra-thick, restaurant-grade material.

Still, it doesn’t feel like a flimsy tin box.

The lid opens smoothly, and the cast iron grates have real weight to them. For this price tier, the panels feel appropriate.

If you want tank-like construction, you’ll spend more. If you want a solid everyday grill without premium pricing, this lands in a reasonable middle ground.

Mesa II vs Original Mesa 415BZ — What Changed?

The Mesa II isn’t a complete redesign — it’s a refinement of the original 415BZ.

Key Differences

• No glass viewing window in the lid. The original version included a lid window. The Mesa II removes it.
• No LED-lit control knobs. Earlier models featured illuminated knobs. The Mesa II uses standard controls.
• Updated flip-up warming rack. Tucks away when not needed.
• Foldable side shelves. Added flexibility for tighter patio spaces.
• Broil Zone integrated into right-side burners. Heat concentration is built directly into the burner layout.
• Pegboard storage retained with two movable hooks included.

The Mesa II trims cosmetic features and leans more into functional improvements and space efficiency.

Mesa II 415BZ vs Weber Spirit

Weber generally wins on heavier construction and long-term brand reputation. The Mesa II competes strongly on features per dollar and overall value.

Pros and Cons

Pros

• Dedicated Broil Zone with noticeable heat separation
• Side burner included
• Pegboard system with movable hooks
• Foldable side shelves
