A 2,000-lb AntiShanty AS-1 Plus Adventure Trailer for Sale in Boulder

If you’ve been waiting for a 2,000-lb hard-sided adventure trailer that a smaller SUV can actually tow, this is the one sitting in Boulder. It’s a 2020 AntiShanty AS-1 Plus, built in Utah by Spectrum Sports / AntiShanty, listed at $35,000. Pre-owned, no land, 60 square feet on the listing. The owner puts it at about 2,000 lbs with a 3,500-lb GVWR, electric brakes, a clean title, and a single owner. New AS-1s start at $39,900; this used Plus is listed under that starting price.

Camp Mode: Hard-Sided A-Frame, No Canvas

Pop the roof and the closed tow box becomes an A-frame. Completely hard-sided — no canvas, no fabric walls. Eric (etgoldgeier) listed it on Tiny Home Builders Marketplace on 05/30/2026 and says camp setup is fast and simple, with tons of airflow and natural light once you’re parked. Easy to tow with smaller SUVs, which is a big part of why they loved it for off-grid camping.

Queen Bunks That Sleep Four

Inside, queen bunk beds sleep four adults. Windows on both sides, stacked bunks, and a spare industrial interior that is all function.

Passenger-Side Kitchen Box, Wallas Diesel, Fridge Slide

The Plus kitchen lives in a passenger-side kitchen box. A custom fridge slide carries a compressor fridge — an ICECO in these photos — with a custom drawer slide for storage. The cooktop is a Wallas diesel heater and stovetop: heat and cooking from the same diesel unit.

Rear Hatch / Toy-Haul

Open the rear hatch and you are looking straight through the bunks to the kitchen, with gear storage under the bed platform. Screens cover the rear hatch, the front door, and the triangle windows.

Power, Awning, and the Rest of the Kit

Power is a 100Ah Expion360 lithium battery and a 2000W Renogy inverter. A 23zero 180° awning is on the trailer (stowed in the listing photos — none of the shots show it deployed), plus an entry step and a spare tire.

Condition

The trailer is in great overall condition. The main cosmetic note is that the exterior decals are weathered and rough in places, which the listing says is common on these trailers over time. Single owner, clean title, Boulder, Colorado 80303.
This is the AS-1 Plus — a different trim from the AS-1 Limited we covered previously.
