Competition in the RV industry is steep, and it’s forced many manufacturers into a race to the bottom. Poor-quality construction has been rampant for years across every segment, from the fanciest Class A motorhomes to the most pared-down teardrop travel trailers. But California-based Ecno Evil is looking to right the ship with an all-new model that’s built seriously tough.

The simply named Unit-1 is Ecno Evil’s debut trailer. The minimalist squaredrop prioritizes function over flashy amenities. Available in two sizes, it’s purpose-built for hardcore off-road adventurers who value durability and versatility. Both models feature a marine-grade HDPE monocoque cabin that serves as both the shell and the interior. Unlike other wood-heavy trailer constructions, it resists impacts and remains flexible under shock (read: everything a trailer experiences on even moderate off-road travel). Plus, it doesn’t rot. The interior can simply be hosed down to keep it clean. The entire cabin rides on a 6061-T6 aluminum frame, which, unlike cheaper steel, won’t rust. A Timbren independent suspension and off-road tires and wheels ensure you can get wherever the wind and your onX app take you.
Ecno Evil claims it’s torture-tested the Unit-1 over washboard roads at 60 MPH, laden with a heavy rooftop tent. It’s even forded 18-inch water crossings with no ingress or structural change. This short video highlights Unit-1’s ability to tackle off-road trails at speed, while soaking up a tree “strike” from accidentally backing up too far (an all-too-common problem many campers have faced):
The compact interior is accessible through a single passenger-side door. Inside, Unit 1 is downright ascetic, designed for maximum versatility. Ecno Evil includes the essentials: A six-inch tri-fold mattress, a 110-volt power outlet, cubby storage, and a roof vent are all standard. But, whether you’re a minimalist overlander, an outdoor photographer, or a nomadic couple traveling with a pup or two in tow, it can easily be configured and optioned out to meet your needs.
The entry-level Unit-1 (measuring 4′ x 8′) stickers for $13,990, while the slightly roomier 5′ x 8′ upgrade starts at $16,490. Ticking every option box adds roughly $3,000 to either model, so expect an all-in price tag for the flagship Unit-1 to run close to $20,000. Both are available for pickup at the company’s shop in Glendale, California with a two-week lead time.
