EarthRoamer LTx and SX 2.0 Review: Heavy-Duty Off-Road Campers

EarthRoamer introduces the LTx and SX 2.0 with 24 V electrical system, 24/18 kWh battery, 9,000 W inverter, up to 1,800 W solar panel; price from 825,000 USD to 1.09 million USD.

After 27 years of developing large off-road campers, EarthRoamer returns with the LTx and SX 2.0: a comprehensive upgrade based on the Ford F-550 and an all-new model based on the Chevy 6500HD. The focus of the upgrade is a 24-volt electrical system for the first time in the company's line, accompanied by a large-capacity lithium-ion battery, a 9,000-watt inverter, and up to 1,800-watt solar charging. The goal is clear: increase energy autonomy, optimize the operation of heavy household appliances, and shorten charging times.

Beneath the protective paint, 43-inch tires, and off-road suspension is a larger-capacity alternator, combined with a new wiring system that recharges the battery faster. The LTx and SX 2.0 are essentially “mobile homes” that can go deep into difficult terrain while maintaining a high level of comfort.

Functional design language

The LTx is an update of the Ford F-550-based EarthRoamer that debuted at SEMA, and it continues the signature “super truck” look: a high nose, high ground clearance, a one-piece cab, and practical details. The LTx has a gross vehicle weight rating (GVWR) of 19,500 pounds, showing off its commercial platform’s ample payload capacity.

The SX 2.0 takes things up a notch in size. The carbon fiber camper shell is larger, measuring 34 feet in overall length and 8 feet wide. The sturdy, boxy shape, coupled with 43-inch tires and off-road suspension, continues to be a hallmark of the EarthRoamer. With an interior height of 7 feet 3 inches, the SX 2.0 offers a “standing up” feel rarely found in off-road campers.

Apartment-like cabins prioritize livability and storage

Both models get a new L-shaped dining set-up that converts into a bed. Up front is a California king-sized bed, upgraded bathrooms, and an Invisacook induction hob hidden under the kitchen counter for more usable space. A larger refrigerator, expanded storage, and an electric-lift TV bring the living space closer to micro-apartment standards.

The LTx is claimed to sleep up to four people, while the SX 2.0 – thanks to its larger body shell – prioritises spaciousness and storage space, making it suitable for longer journeys.

Heavy duty transmission, aimed at a wide load range

EarthRoamer continues to choose durable mechanical components from two American manufacturers. The LTx uses a 6.7-liter Power Stroke turbocharged diesel V8 mated to a 10-speed automatic. The SX 2.0 is equipped with a 6.6-liter Duramax diesel V8 mated to an Allison 6-speed automatic. Both are built on heavy-duty chassis (Ford F-550 and Chevy 6500HD), a choice suitable for the heavy-duty demands of the camper shell, water, fuel, and equipment.

On the SX 2.0 side, a 100-gallon fuel tank, two 5-gallon black sump tanks, and a 7-foot, 3-inch cab ceiling suggest the larger model's focus is on range and long-term comfort. At 34 feet long and 8 feet wide, the SX 2.0 demands adequate work space, but in return it offers superior equipment-carrying capacity.

Independent power technology: 24 V, large battery, 9,000 W inverter

The most notable technical highlight is the new 24 V electrical system. Compared to the previous configuration, the wiring diagram has been redesigned to charge the lithium-ion battery pack faster: 24 kWh on the SX 2.0 and 18 kWh on the LTx. The 9,000 W inverter (three times the capacity of the previous generation) allows for simultaneous operation of multiple household appliances. On the roof, the solar panel system can reach 1,800 W, reducing the dependence on external power when camping for a long time. EarthRoamer also uses a larger capacity generator to increase charging speed when the engine is running.

Safety and assistive technology

The announcement focused on the mechanical and electrical underpinnings; the automaker didn’t detail driver assistance packages or crash ratings. Given the heavy-duty chassis and off-road intent, the EarthRoamer duo prioritized durable components like 43-inch tires, off-road suspension, and carbon fiber bodywork (on the SX 2.0) over advanced driver aids.

Price, location and display schedule

The LTx starts at $825,000. The SX 2.0 starts at $1.09 million. EarthRoamer requires a $175,000 deposit before it begins customizing the vehicle. Both will be on display at SEMA, Las Vegas Convention Center, from November 4 to 7, 2025.

Conclusion: Outstanding strengths, requiring a commensurate budget

With a 24-volt electrical system, large battery, 9,000-watt inverter, and up to 1,800-watt solar panel, the LTx and SX 2.0 solidify EarthRoamer's place in the heavy-duty off-road camper category. The LTx is for those who want a balanced size-to-comfort ratio on the Ford F-550 platform, while the SX 2.0 is for those who need maximum space and range.

Pros: Heavy-duty mechanical platform, strong independent electrical configuration, well-arranged interior and premium materials. Cons: High purchase price and massive size (especially with the SX 2.0) requiring adequate operating space. Still, for customers willing to invest, the new EarthRoamer duo offer a truly “luxury but practical” camping experience.
