7’ wide enclosed trailers offer increased interior space and load capacity without requiring a full jump to an 8.5’ wide platform. At TrailersPlus St. Lucie, we carry 7x12, 7x14, and 7x16 tandem axle models for buyers who need more room to haul equipment, tools, or recreational gear. These trailers are fully enclosed and reinforced to handle heavier loads while maintaining solid tracking and braking performance. Local contractors, landscape crews, and small business operators across the Treasure Coast rely on this size for daily transport demands.

Built to Haul Heavy Equipment, Securely
This trailer size is ideal for those moving bulkier items—commercial mowers, multiple motorcycles or ATVs, or crew-size tool and supply loads. The added width allows for easier access and better layout inside the trailer, while tandem axles provide improved load balance, smoother braking, and better performance on longer hauls or rougher roads. Standard features include a welded steel frame, undercoated chassis, and ¾” exterior-grade plywood floor. Each model also includes a one-piece aluminum roof, LED lighting, and radial tires.
Tandem Axle Builds for Stability and Payload
All 7’ wide trailers at our St. Lucie dealership come in tandem axle configurations—7x12, 7x14, and 7x16 sizes—designed to carry more weight safely and comfortably. Spring-assisted rear ramp doors make loading and unloading simple, while a side entry door with cam-bar lock provides easy access. A spare tire is mounted standard. Inside, 3/8” plywood walls offer a ready surface for E-track installation, shelving, or custom gear setups.
Tiered Models with Upgraded Features
We offer Victory, LoadRunner, and Pro Series trailers in this size category:
- Victory: Welded hinges, seamless aluminum roof, and 1-year bumper-to-bumper warranty.
- LoadRunner: .030" aluminum siding, aero vents, added interior height, and a 5-year roof warranty.
- Pro Series: Dexter torsion axles, upgraded tie-down points, extended stone guards, and 3-year bumper-to-bumper warranty with lifetime roof protection.
All models are built to the same core Interstate quality standards for structural integrity and long-term use.
Built on the Interstate DuraFrame™ Platform
Each 7’ wide trailer is constructed using the Interstate DuraFrame™ system: hat-bow vertical studs, through-frame tongue, gusseted reinforcements, and Quadra-Sealed™ roof seams come standard. All door hardware is welded, not bolted. Electrical wiring is internally routed for protection and a clean finish. Every unit includes diamond plate stone guards to shield against debris and extend exterior durability—critical for Florida’s mixed road surfaces and coastal exposure.
Financing, Rent-to-Own, and Warranty Support in St. Lucie
You can apply for traditional trailer financing through Sheffield Financial or Rock Solid Funding, often with accessory add-ons included in the same loan. Rent-to-own is also available with no credit check and fixed monthly payments. Every trailer purchase comes with two free 40-point inspections—scheduled at 12 and 24 months—handled by our on-site service team. All warranties are backed by the manufacturer, covering structure, materials, and workmanship depending on the model tier.
