Turnkey Jobsite Delivery in 3 Seamless Steps
We coordinate transport from factory dispatch straight to your job site coordinates, managing oversize permits, highway transport, and site staging.
Route & Permit Dispatch
Logistics team plans state highway route permits and oversize escort requirements to your exact ZIP code coordinates.
On-Site Placement
Precision tow vehicle delivers unit directly onto site pad. 4 mechanical jacks level the chassis on unpaved terrain.
Plug & Play Operation
Connect commercial power hookup to exterior junction box and turn on the HVAC. Your field office is 100% operational in hours.
Three Structural Pillars
That Define Our Quality.
We design and manufacture modular mobile workspaces that endure rough handling, remote territory deployment, and continuous commercial duty.
1. We Understand Field Operations
Built around how site crews actually work.
Every floor plan is engineered around operational reality: ergonomic workstation spacing, heavy-duty electrical outlets right where monitors and chargers plug in, durable boot-resistant flooring, and high-efficiency HVAC that cools down an office in 100°F+ jobsite heat in minutes.
2. We Build with Industrial Purpose
No lightweight domestic shortcuts.
Unlike converted travel trailers that break down after one project, Capelton units are manufactured with heavy-gauge structural steel I-beams, 3-inch fire-rated sandwich walls, and a continuous seamless aluminum roof designed for multiple project lifecycles.
3. Direct Logistics & Turnkey Dispatch
From factory fabrication directly to your site coordinates.
We eliminate dealer markups and middleman delays. Our dedicated logistics dispatch coordinates freight, oversize transport permits, and scheduled jobsite arrival, backed by comprehensive direct factory warranties on chassis and structural frame.
