2025 Opus OP15 vs 2024 Opus OP2

Detailed Comparison

The 2025 Opus OP15 and 2024 Opus OP2 represent two compelling choices for RV enthusiasts. Let's break down what sets them apart.

Starting with size, the Opus OP15 measures 18.0 ft long and tips the scales at 2,700 lbs dry weight. The Opus OP2 comes in at 14.5 ft with a dry weight of 3,100 lbs. That gives the Opus OP15 roughly 3.5 extra feet of length.

Capacity-wise, expect to sleep 4 in the Opus OP15 versus 5 in the Opus OP2. With 0 and 1 slide-outs respectively, the parked floor plans differ significantly.

Tank capacities are a key off-grid consideration. The Opus OP15 carries 2 gal of fresh water, 21 gal gray, and 3 gal black. The Opus OP2 offers 17 gal fresh, 22 gal gray, and N/A black. The Opus OP2 has the edge for extended dry camping.

Budget-wise, the Opus OP15 is listed at $9,000 compared to $29,000 for the Opus OP2.

For occasional getaways, the more affordable and nimble option usually makes the most sense. For two travelers seeking comfort without excess, the smaller footprint often wins.

Ultimately, both rigs have their merits — test drive each one and see which floor plan speaks to your lifestyle.

When it comes to water management, tank capacity plays a major role in how long you can stay off the grid. The 2024 Opus OP2 carries 17 gallons of fresh water versus 2 gallons in the 2025 Opus OP15, providing an extra 15 gallons for longer boondocking stays. Gray water capacity favors the 2024 Opus OP2 at 22 gallons versus 21 gallons, which directly affects how often you need to find a dump station.

Electrical systems are increasingly important as RVers rely on more electronics and appliances. Both units arrive with 100W of solar capacity, providing a solid foundation for off-grid power generation. Battery banks are matched at 50Ah, so overnight power reserves will be similar in both units. The 2025 Opus OP15's 1000W inverter can handle heavier loads than the 500W inverter in the other unit, which matters if you plan to run a microwave, coffee maker, or hair dryer without shore power.

For solo travelers and couples who value maneuverability, the 2024 Opus OP2 with its more compact footprint will be easier to navigate through tight campgrounds and mountain passes. Families with children should lean toward the 2024 Opus OP2, which sleeps up to 5 and provides more flexibility for overnight guests. Full-time RVers who spend extended periods off-grid will benefit most from the 2025 Opus OP15's power setup and the 2024 Opus OP2's water reserves, as these directly impact daily comfort and independence from hookups. Weekend warriors and seasonal campers who primarily stay at full-hookup campgrounds may find that the differences in tank sizes and power systems matter less, allowing them to focus on floor plan preference and overall comfort instead.

From a value perspective, the 2025 Opus OP15 at $9,000 MSRP represents a $20,000 savings over the 2024 Opus OP2 at $29,000, a 222% price difference. Breaking it down per sleeping position, the 2025 Opus OP15 costs roughly $2,250 per berth while the 2024 Opus OP2 comes in at $5,800 per berth. On a cost-per-foot basis, the 2025 Opus OP15 runs about $500 per linear foot versus $2,000 for the 2024 Opus OP2, which helps contextualize the value each unit delivers for its size. Since both models come from Opus, buyers can expect consistent build quality, a shared dealer network, and comparable warranty coverage, which simplifies the after-purchase ownership experience.
