When shopping for a premium Mercedes-Benz Sprinter camper van, two names consistently emerge: Grech RV and Airstream Interstate. Both brands are renowned for their craftsmanship and connection to the Sprinter platform, but they cater to buyers with distinct needs and expectations. If you’ve been wondering which Class B is right for you, understanding the differences in design, performance, and ownership experience will help guide your decision.
Chassis & Model Options
Both brands share a strong foundation: the Mercedes-Benz Sprinter. Airstream offers models like the Interstate 19, available on the shorter 144” wheelbase, and the Interstate 24GT/GL, which features the longer 170” chassis. These appeal to travelers who want a choice between agility and interior space. Grech RV also offers three distinctive Sprinter-based models: the Turismo-ion (144”), the Terreno-ion (170”), and the Strada-ion (170” Extended). Grech emphasizes ride quality by including air suspension as standard on the Strada and the Terreno, something that is optional or limited in other builds.
Power & Off-Grid Capability
For many buyers, energy independence is a key consideration. For Model Year 2026, Airstream has introduced the Advanced Power System as standard across all Interstate and Atlas models. This features a 10.3 kWh lithium battery with a built-in heater, a 3,000W inverter, and the capability to run multiple appliances simultaneously. Buyers can also upgrade to the Advanced Power Plus system, available only on select Interstate models, which expands capacity to 17.2 kWh. This is a significant step forward for Airstream, but the larger capacity requires an optional upgrade.
Grech RV takes a more robust approach by including the GRECH POWER™ system standard on all 2026 models. This UL-certified 51V Lithionics® lithium-ion battery delivers 16,896 Wh (≈16.9 kWh) of energy as standard. Grech’s system supports up to 14 hours of rooftop A/C use on battery power alone, recharges 50% faster than 12V systems, and integrates with solar panels and a secondary alternator. Both brands use ARCO Zeus alternator technology, but Grech highlights faster recharging and more consistent off-grid performance.
Utility & Convenience
The way utilities are accessed can influence everyday use. Airstream typically relies on multiple exterior service compartments, which are practical but visibly disrupt the exterior design. Grech RV integrates its utilities into a patented concealed stainless-steel center with integrated lighting, making setup simpler and more refined in appearance. For buyers who value ease of use as much as style, this can be a deciding factor.
Interiors & Comfort
Step inside and the differences continue. Airstream’s interiors reflect its iconic design language: clean lines, modern finishes, and efficient use of space. Its wet bath setup maximizes function in a compact footprint. Grech RV focuses on handcrafted comfort, using Ultraleather seating, hardwood cabinetry, and ambient LED lighting. Its wet baths are slightly larger than Airstream’s and include a window with a privacy shade, offering a more residential feel. For some, Airstream’s sleek minimalism is ideal; for others, Grech’s emphasis on premium comfort is the clear winner.
Build Quality & Craftsmanship
Airstream is one of the most recognized names in RVing, backed by decades of history and a reputation for quality. That legacy brings prestige, but as a larger manufacturer, consistency can sometimes vary. Grech RV, with more than 42 years of experience in the industry, is a family-owned builder with roots in luxury bus manufacturing. Every coach is produced with boutique-level attention to detail, which customers often describe as a defining factor in their purchasing decision.
One Grech RV owner summed up their experience this way:
“Best family investment we’ve ever made. We looked for a while into which van would be best for our family of 5 children and all our activities — snowboarding, cheerleading events, camping, just to name a few. Through months of research, we finally decided to make the investment with a Grech Mercedes Sprinter Strada Ion. It has allowed our family to do so many more things as a family, and all the kids love it.”
This review highlights one of the most important aspects: real-world usability. For this family, the Strada Ion wasn’t just a purchase—it became a tool for creating new experiences together.
Ownership Experience
Beyond specs and layouts, ownership is where differences can become most evident. Airstream buyers often cite the confidence of purchasing from a legacy brand, with strong resale recognition and a widespread dealer network. For 2026, Airstream offers a 2-year limited coach warranty, 5-year/75,000-mile chassis warranty, and 5-year/100,000-mile engine coverage. Grech RV owners point to unmatched warranty coverage, attention to detail, and responsive customer service. Grech’s warranty includes 3 years/36,000 miles on the coach, plus 5 years/100,000 miles on the Mercedes-Benz engine—longer coach coverage than Airstream. Just as important, Grech’s 51V battery system is engineered to outlast and outperform Airstream’s 12V platforms, offering buyers not only more efficiency on the road but also greater confidence in long-term ownership value.
Who Should Choose Each?
- Airstream Interstate is best for those who want the prestige of an iconic brand, appreciate minimalist modern interiors, and value the efficiency of a legacy name in RVing.
- Grech RV is best for travelers who want handcrafted quality, advanced energy systems for true off-grid adventures, and a design that emphasizes comfort and refinement.
The Road Ahead: Making Your Choice
The decision between Grech RV and Airstream Interstate ultimately depends on lifestyle. Airstream brings its iconic name and efficient design, making it a great option for those drawn to tradition and prestige. Grech RV offers innovation, craftsmanship, and unmatched energy systems, setting a new benchmark for Sprinter-based Class B motorhomes. Both are exceptional choices—but for those who want refined comfort and long-term reliability, Grech RV stands out.
