Previous owner used this as a toy hauler, we cleaned out all the sand and added shelving to make it our work trailer. It would hold our tool chest, table saw, compressor, and bins of tools and supplies, along with drywall, lumber, etc.
Body is 13' long, 6' 6" wide. Length to hitch is 17 feet, and it has a swivel-down wheel.
Back loading door is 63" tall by 61" wide. Interior is 72" tall, 9' 10" from rear door to front cabinet, and 59" wide between the wheel wells. Smaller width with shelves included, forgot to measure that.
Three ceiling mounted cabinets on one side, and two on the other. Front cabinets have a divider shelf inside and hookups for a sink (from its toy hauler days, we never used it). LED tail lights.
Dual-axle is great, easily towed this with my crossover SUV.
