2025 Thor Rize 18M vs 2025 ModVans CV2

Detailed Comparison

Two noteworthy RVs face off: the 2025 Thor Rize 18M and the 2025 ModVans CV2. From dimensions to amenities, here's the full breakdown.

Starting with size, the Thor Rize 18M measures 19.0 ft long and tips the scales at 6,600 lbs dry weight. The ModVans CV2 comes in at 18.0 ft with a dry weight of 8,400 lbs.

Capacity-wise, expect to sleep 3 in the Thor Rize 18M versus 4 in the ModVans CV2.

Tank capacities are a key off-grid consideration. The Thor Rize 18M carries 19 gal of fresh water, 13 gal gray, and 5 gal black. The ModVans CV2 offers 26 gal fresh, 12 gal gray, and 5 gal black. The ModVans CV2 has the edge for extended dry camping.

Budget-wise, the ModVans CV2 is listed at $170,000 compared to $170,000 for the Thor Rize 18M.

For boondocking, the model with superior solar and battery setup will keep you comfortable off the grid longer. For occasional getaways, the more affordable and nimble option usually makes the most sense.

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 2025 ModVans CV2 carries 26 gallons of fresh water versus 19 gallons in the 2025 Thor Rize 18M, providing an extra 7 gallons for longer boondocking stays. Gray water capacity favors the 2025 Thor Rize 18M at 13 gallons versus 12 gallons, which directly affects how often you need to find a dump station. Black water tanks are evenly matched at 5 gallons each, meaning dump station visits will be equally frequent for both rigs.

Electrical systems are increasingly important as RVers rely on more electronics and appliances. With 400W of solar, the 2025 ModVans CV2 outpaces the 2025 Thor Rize 18M's 250W setup, offering better energy independence away from hookups. Battery storage gives the edge to the 2025 ModVans CV2 with 500Ah versus 350Ah, translating to longer run times for lights, fans, and charging devices overnight. The 2025 ModVans CV2's 2000W inverter can handle heavier loads than the 1500W 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 2025 ModVans CV2 with its more compact footprint will be easier to navigate through tight campgrounds and mountain passes. Families with children should lean toward the 2025 ModVans CV2, which sleeps up to 4 and provides more flexibility for overnight guests. Full-time RVers who spend extended periods off-grid will benefit most from the 2025 ModVans CV2's power setup and the 2025 ModVans CV2'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.

Both models carry the same $170,000 MSRP, so the buying decision comes down purely to features, floor plan preference, and brand loyalty rather than budget constraints. It is also worth considering that Thor and ModVans have different dealer networks and warranty programs, which can significantly impact your long-term ownership experience and resale value down the road.
