Horse Trailer & Cargo Conversion RVs for Sale
Looking for the ultimate cargo conversion RV for sale near Ottawa? Whether you are looking to build a custom mobile workshop or need a ruggedized horse trailer conversion with living quarters, you need a foundation that can handle the weight. At Big Country RV in Carleton Place, we specialize in high-capacity Toy Haulers like the 2026 Grand Design Momentum and Keystone Fuzion Impact, which offer the industrial-grade frames and "no-wheel-well" garages required for serious customization.
Standard trailers aren't built for the shifting weight of livestock or the concentrated load of heavy machinery. Our 2026 inventory features 101-inch wide-body chassis and frame-welded 5,000 lb. tie-down systems that provide the structural integrity you need for a safe conversion. From the equestrian trails of the Lanark Highlands to mobile contracting sites in Kanata, these rigs are the region's top choice for those who need a professional-grade workspace or a custom animal-transport setup without sacrificing 5-star living amenities.
Why Big Country RV is Ontario’s Conversion Headquarters
We stock the "heavy-haul" builds that provide the perfect blank canvas for your specific needs:
-
"No Wheel Well" Garage Design: We prioritize 2026 models like the Momentum G-Class, featuring a flush-floor design. This is critical for horse trailer conversions or installing custom cabinetry and tool benches without losing floor space to interior fender wells.
-
Commercial-Grade Flooring: Our 2026 units feature Stratamax™ Ultra or fiber-backed linoleum. These materials are engineered to be scratch, stain, and gouge resistant—essential for high-traffic cargo use or easy-to-clean animal stalls.
-
Massive Cargo Capacities: Don't get sidelined by a weak axle. We stock units with 7,000 lb. Dexter® E-Z Lube® axles and G-rated tires, offering the payload capacity needed for heavy tools, specialized equipment, or equine transport.
-
Aggressive "$0 Down" Financing: Building your dream conversion is an investment. We offer $0 down financing (OAC) with flexible terms, allowing you to keep your capital for the custom work while enjoying a low bi-weekly payment on the base unit.

Custom Conversions: Frequently Asked Questions
Can a Toy Hauler really be converted for horses? While not a dedicated horse trailer from the factory, many of our Grand Design Momentum customers use the 13' to 15' garages as a starting point for "Comfort Package" conversions. The reinforced ramp doors (rated for 3,000 lbs+) and the heavy-duty I-beam frames provide the necessary strength. Our Carleton Place service team can advise on the best models for ventilation and floor reinforcement.
What is the best model for a mobile workshop or office? The 2026 Keystone Fuzion Impact 367 is a top choice for contractors and "makers." It features a 14-foot separate garage, allowing you to keep your tools and dust separate from your living area. With built-in 30-gallon fuel stations and generator prep, you have a self-contained power plant for your pneumatic tools and electronics.
How do I handle the weight of heavy cargo? Every unit we sell includes a professional weight-distribution consultation. For "Heavy Cargo" or conversion use, we recommend our 101" Wide-Body SuperChassis models. These provide a more stable jack stance and wider rail placement, ensuring your rig remains level and safe on the Highway 7 corridor.
