Product overview

What the ZH3005Y Actually Offers

This is a combination unit: one side runs on propane gas (two 12,000-BTU stainless steel burners), the other side burns charcoal, and an attached offset smoker box on the end adds a third cooking zone, plus a separate 10,000-BTU side burner for sauces or sides — 34,000 BTU total gas output. The total advertised cooking area is 1,020 sq. in., broken down as 333 sq. in. gas grilling area, 333 sq. in. charcoal grilling area, 157 sq. in. warming rack, and 197 sq. in. in the offset smoker.

Build details from the listing and manual: piezo push-button ignition, a 3-level adjustable charcoal pan for controlling heat intensity, 3.3 lb charcoal capacity in the main grill and 1.5 lb in the smoker box, a side access door on the smoker for ash removal and refueling, alloy steel construction in a black finish, and a fairly large footprint (about 67.7 in. wide, 23.4 in. deep, 46.2 in. tall) at roughly 87 lbs assembled.

Notably, we found this exact model number and spec sheet also sold as the 'Royal Gourmet ZH3005Y 2-Burner Gas and Charcoal Combo Grill with Offset Smoker & Side Burner' at Wayfair and Walmart — meaning this appears to be the same physical product distributed under two different storefront brand names. That's useful for research purposes: it means there's a slightly larger pool of customer reviews across both listings than you'd get from a single-brand product.

Pulling from that shared review pool (via Walmart's customer reviews for the Royal Gourmet-branded version of this same grill), feedback skewed positive on two specific points: buyers found it straightforward to assemble, aided by widely available YouTube assembly videos, and multiple reviewers specifically praised the smoker function, with one describing it as smoking 'PERFECTLY' and having plenty of cooking space for a group. One Amazon-reported rating summary we found put this listing at roughly 3.9 out of 5 stars, though you should confirm the current rating directly on the listing since it changes over time.

We did not find independent lab testing (temperature-hold accuracy, smoke-ring consistency, long-term rust resistance) from a major outlet for this model — the evidence here is real aggregated customer feedback plus manufacturer specs, not third-party lab verification, so weigh it accordingly, especially for anyone planning serious low-and-slow smoking rather than casual backyard use.

Good fit for

Good for buyers who want gas convenience and charcoal/smoke flavor in one unit without buying a separate dedicated smoker.
A strong fit for groups, given the 1,020 sq. in. total cooking area across four zones (gas, charcoal, warming rack, smoker).
Less ideal for anyone who wants a dedicated, temperature-stable offset smoker for serious low-and-slow barbecue — this is a combo unit, not a specialist smoker.

Check before buying

Confirm current Amazon and Walmart star ratings and read recent reviews for rust, paint/seal quality, or smoker temperature-holding complaints.
Check whether the identical Royal Gourmet-branded ZH3005Y is priced differently at the time you're buying, since it's the same product.
Verify what's included for charcoal management (ash pan, tools) versus what you need to buy separately.
Look at assembly-time reports in reviews — this is a large, heavy (about 87 lb) unit with multiple sub-assemblies (grill, smoker box, cart).
If smoking is your primary use case, check reviews specifically for temperature-holding consistency in the offset box, since that's a common weak point on combo-style smokers at this price.
