2025 Grech Terreno Class B Motorhomes for Sale 

Overview

The Grech RV family of Class B motorhomes is highlighted by the 2025 Grech Terreno. It has exceptional quality, top-notch craftsmanship, and a level of attention to detail seldom seen in RV building, exemplifying what a real luxury Class B motorhome should be. The Terreno vehicles have more luxurious features as standard equipment than any other Class B vans currently available. Grech adds a custom-built body to the Mercedes Sprinter 3500XD chassis, bringing back the era of hand-crafted coachbuilding and unmatched fit and quality. The Terreno also offers both rear-wheel drive and four-wheel drive versions of the Sprinter chassis, for those clients who may need extra traction. There are two floorplans available: the Lounge and the Tour, each with unique advantages. The Lounge versions can accommodate up to 9 people for seating, where the Tour offers a few more lifestyle options such as more storage and floorspace, while still offering seating for 7 people. The interiors of the Terreno vehicles are also stocked with a bevy of five-star amenities. Ultraleather surfaces, real wooden doors and cupboards, gourmet kitchens, and soft LED lighting provide an atmosphere akin to that of the finest hotels. The new Timberline diesel-fueled Hot Water and Heating System, the Firefly integrated control system, and in the Terreno-ion versions, a unique Lithium-battery power system are examples of contemporary high-tech features. Amazing ride quality is provided by the custom air suspension, and the exterior bodywork incorporates hideaway stainless-steel panels to conceal the RV connections and utility centers, adding to the vehicle's slick look. When you go on an adventure in a Grech, industry-leading warranties and round-the-clock technical assistance provide you a genuine sense of security. Grech is a family-owned, independent business that is dedicated to giving its customers top-notch goods and services. Since McClain's RV Superstores shares these values, we decided to collaborate with them. Come experience the remarkable luxury Class B RVs firsthand at any of McClain's RV Superstores locations.

Floorplans

Two models, the 2025 Terreno and the Terreno-Ion, make up the Terreno family, and both come in two-wheel drive and four-wheel drive variations. Except for the power and drive systems they employ, all variants share the same Mercedes-Benz Sprinter 3500XD 170" non-extended high-roof chassis and are essentially similar. When you are away from shore power, the Terreno and Terreno 4x4 models' Ultra Quiet Cummins Onan 2.5 KW propane-powered generator provides electricity for your coach. For ample power while you're on the go, the generator is coupled with a 2,000-watt Xantrex inverter, two lithium batteries, and a 300-watt solar system. The Lithionics battery system, the only one UL has tested and authorized, is used in place of the generator in the Terreno-Ion and Terreno-Ion 4x4 variants. The most cutting-edge energy storage system for a Class B motorhome is this one. The Lithionics batteries have a capacity of 1,260-amp hours, and they are charged while the engine is running by an additional 280-amp alternator. You may still use the Zamp 300-watt solar system in conjunction with the inverter's move to a 3,000-watt Xantrax model to get clean lithium-based electricity for prolonged off-grid periods. The Lounge and the Tour are the two distinct floorplans featured in all Terreno collection variations. The Lounge layout optimizes the number of passenger seats available by adhering to the "more is better" principle. The two captain's chairs in the front of the vehicle may individually turn to face the inside of the car while it is parked. There are two more roomy, separate recliner-style chairs as you descend from the vehicle's cab floor, along with a mounting place for a fold-down standing table. For maximum comfort, each of these can swivel and recline. Next, proceed to the galley, where you will find the two-burner stove top, deep bowl sink, and countertop. In the bottom cabinets is a convection microwave, and just next to it is a refrigerator. There are several overhead cabinets throughout the whole cabin, and the galley also has additional storage. Your personal wet bathroom is located on the other side of the kitchen. When the circular door opens, a sizable sink area is on your left. On your right is a porcelain toilet, and the faucet in the sink can be adjusted to function as a shower head. Two opposing seats on either side of the coach, facing each other, may be found back outside the restroom as you travel towards the back of the vehicle. A three-person, folding sofa is located at the rear. Together with the two chairs, this may be folded flat to create a roomy king-size sleeping space. With this selection of chairs, the Lounge layout can accommodate up to nine people. The Tour model is different from the Lounge in a few ways. There is now a sizable garment closet and full-size fridge adjacent to the bathroom after the two chairs that were formerly behind the cab area were moved. The two seats and sofa in the back, as well as the galley and bathroom, stay the same. Now that the pedestal table mount is located at the back of the bus, you have room to read, play games, etc. A TV mount is also available, facing the couch. While the Tour model accommodates up to 7 passengers, there's ample space for endless adventure!

Exterior

The elegant look of the 2025 Grech Terreno range of RVs is intended to thrill its owner, whether traveling down the highway or remaining stationary at the campsite. The Grech bespoke fiberglass body package only accentuates the stunning outward aesthetics of the Mercedes-Benz Sprinter 3500XD chassis. The Terreno series comes in three exterior colors. The Iridium silver has the enduring Mercedes “look” that has served as a brand identifier for years. The Tenorite Grey color has a dark, smoky appearance that conjures the idea of an impending storm front, while the Grey White color has a lovely alabaster tone to it. The 3.0-liter V6 diesel engine, which offers lots of horsepower but also exceptional fuel efficiency, is one of the other chassis elements. Mercedes selectable four-wheel drive allows the driver to engage the front wheels at the push of a button, granting more traction and stability in slippery situations. The motorized step, which retracts into the bodywork when not in use, can be seen as you go along the side of the car. The substantial motorized awning extends across a sizable area, has built-in LED lights, and has wind sensors that force it to retract automatically if the wind speed becomes high enough to cause damage. Cable TV, propane, municipal water, and 30-amp shore hookups are all connected to your external utility center. This is deftly concealed behind a panel made of stainless steel that seamlessly integrates into the bodywork. A TV can be plugged in using the outer power connections, and there is even an outdoor shower for washing off after a strenuous day spent outside. The Dometic low-profile 13,500 BTU air conditioner and extra-large 300-watt solar panel are both located on the roof. The Timberline Diesel system makes use of the vehicle's gasoline to instantly provide heat when needed while also heating your water and the coach itself. One of the greatest in the business, the bespoke air suspension offers a comfortable and elegant ride quality regardless of the state of the roads. Additional external features comprise a 5,000-pound tow hitch, backup cameras, rear sensors, and sleek glossy wheels for a polished appearance.

Interior

One of the most opulent interiors in the RV business is that of the 2025 Grech Terreno. Many of the driving aids are designed to operate hands-free in the Mercedes cab area, letting you maintain both hands on the steering wheel. There are several safety aids at your disposal in addition to a top-notch in-dash navigation system. Since the cars' flooring is made of a Chilewich woven cloth rather than the vinyl seen in other brands, they have a highly distinctive design. This woven cloth is stronger and gives off a definite sense of richness. Along with the LED accent lighting fitted under the cupboards, the soft-touch walls and headliner are present throughout the whole cabin. Speaking of the cabinets, they have radius-opening doors for greater room and are created by hand from Swiss Chrono hardwood. The entire fiberglass insulation behind the walls, which also gives you excellent temperature control whether it's hot or freezing outside, is responsible for the cabin's overall quietness while you drive. When you are camping, the screen door at the entryway keeps pests out while still allowing air to flow into the cabin. The stainless-steel sinks in the galley have matching faucets and fixtures, and the worktops are quartz. You will find a foot-flushing ceramic toilet, a molded basin with a vanity mirror, and a handheld shower head in the wet bathroom. For times when you need to hang up some clothing in the locked restroom, there is even a retractable clothesline. A Bose soundbar and a 24" high-definition TV are provided for your amusement. There are several USB outlets throughout the cabin, and the TV mounts are pre-wired for cable and satellite. The back sofa contains memory foam for added comfort and is covered in Ultraleather, which is velvety and long-lasting. Your Firefly Integration Panel has control over every system on the coach. You can effortlessly manage all electrical, plumbing, lighting, and awning systems using the intuitive touch-screen device.
