The Rio Grande sits atop a 9.7 m (32 ft) gooseneck trailer, which is less than a meter (or a couple of feet) longer than the Custom 30 Foot House. This isn't a lot, but in the small living scene, in which homes can measure as little as 9 sq m (96 sq ft), it's sure to make a difference. The gooseneck trailerwas chosen by Rocky Mountain Tiny house boss Greg Parham to offer its owners more stability when towing.

Comprising 20.25 sq m (218 sq ft) of primary living space and 6.5 sq m (70 sq ft) of loft space, the Rio Grande features a river motif formed by taking a propane torch to the cedar siding to create the outline of a flowing river. Inside, rocks collected by the owners were inlaid into the countertop. Reclaimed wood was used for the front door, fold-down porch, rear door, and picture frames.

Like its predecessor, the Rio Grande packs more amenities than you might expect from a towable dwelling. The dining area features folding seating that reveals storage space, in addition to a fold-up table, while the kitchen area boasts a full-sized refrigerator, washer and dryer, wood-burning stove, and a propane range cooker. The kitchen leads onto a bathroom – separated by a sliding door – and this includes a full-sized bath and composting toilet.
