ATC StŌ 350 Toy Hauler

ATC StŌ 350 Toy Hauler

The versatile toy hauler/cargo trailer hybrid built for adventure.


Is it a toy hauler or a cargo trailer? Why can’t it be both! The ATC Stō 350 is the upfitted cargo trailer that you don’t have to do the work on. It’s the toy hauler for those who don’t need all the bells and whistles of a higher-priced living quarters. It’s the highly versatile, configurable adventure toy hauler capable of growing with you.

Just the Way You Like It

With 178 feet of configurable wall space and an upper and lower modular track system, you can add or remove cabinets and furniture as often as you need. ATC offers a variety of cabinet sizes, fold-down tables, sofas, and more that you can add on. You’re not locked into one configuration, either. Simply unscrew and reattach exactly where it works best for you.

Built for Smaller Towing

The 12′ model has a single 3500-pound axle, while the 14′ model has a single 5200-pound axle. The 80-inch total width and aluminum frame makes the ATC Stō 350 toy hauler ideal for towing behind mid-size SUVs and compact trucks.

Designed to Grow With You

The Stō 350 blurs the lines between cargo trailer and toy hauler. To meet a need for the growing trend of cargo trailer conversions, ATC made it easy — and more efficient — by doing the work for you. Load it up with all your toys for a camping, hunting, or fishing adventure. Or remove everything and use it as a standard cargo trailer. The choice is yours.

Packages Available

The off-road package includes all-terrain tires, increased ground clearance, and a Jeep-style fender. Upgrade to the 30amp electrical package for more power capacity, A/C prep, and solar prep. Multiple module packages can add cabinets, microwave, shelves, and more. Or you can pick and choose the add-ons you want.
