How Green River Builds a Park Model Cabin in 3 Weeks

One of the most common questions we get from campground owners and buyers is: “How long does it actually take?” The answer tends to surprise people. From the day we start your cabin in our Campobello, South Carolina factory to the day it’s delivered to your site — we typically build a park model cabin in three weeks or less.

Here’s a look at what goes into that timeline and why it’s possible at Green River Cabins & Cottages.

Why Speed Matters in Park Model Manufacturing

If you’re a campground operator adding cabins for the season, timing is everything. Miss your spring opening and you’ve lost months of peak revenue. Traditional site-built construction — with permitting delays, subcontractor scheduling, and weather dependencies — can take 6–12 months per cabin. A factory-built park model cabin eliminates most of those variables.

Because we build indoors, in a controlled environment, our construction timeline doesn’t care about rain, frost, or subcontractor no-shows. Every day in our factory is a production day.

The Build Process: Week by Week

Week 1 — Structure and Shell

The build begins with the chassis and floor system. Our team assembles the structural frame, lays the subfloor, and frames the walls using lumber optimized for the floor plan. By end of week one, your cabin has its full exterior shell — walls, roof structure, and sheathing — ready for the next phase.

All Green River units are built to HUD code and ANSI A119.5 standards, the national construction and safety standard for park model RVs. This isn’t a shortcut build — it’s a precision-engineered process we repeat consistently across every unit.

Week 2 — Systems and Insulation

Week two is where the cabin gets its guts. Electrical wiring, plumbing rough-in, HVAC ductwork, and insulation all go in simultaneously with different crews working in concert. Our factory floor is organized to avoid bottlenecks — while one crew is running wire, another is running pipe, and a third is installing insulation batts.

Exterior siding, windows, and doors are installed during this phase as well, so by week two’s end the cabin is fully enclosed and weathertight, with all rough systems in place.

Week 3 — Interior Finish and Inspection

The final week is where your cabin becomes recognizable as a home. Drywall, flooring, cabinetry, trim, fixtures, appliances, and paint all come together. Our craftsmen take pride in this phase — we’re building something people are going to live in, vacation in, and remember.

At the end of week three, the unit goes through our in-house quality inspection before scheduling delivery. We walk every system and every finish detail before the cabin ever leaves our facility.

Delivery and Setup

Park model cabins are built to be transported. Your Green River cabin ships as a single unit on a specialized transport trailer (park models are up to 400 sq ft under ANSI A119.5, with loft additions possible). Setup on-site typically takes 1–2 days for blocking, leveling, utility connection, and any porch or step installation.

If your site is prepped and utilities are stubbed in, you can have a fully installed, move-in-ready cabin within days of factory completion.

What Buyers Tell Us

First-time buyers consistently say the same thing: “I didn’t expect the quality.” The combination of speed and craftsmanship surprises people who assume faster means cheaper. The reality is that factory construction is more consistent than site-built work precisely because every step happens in a controlled environment with trained crews doing the same processes repeatedly.

See It for Yourself

We invite campground operators, investors, and personal buyers to tour our factory in Campobello, SC. Walk the production floor, see units at every stage of construction, and talk directly with our team about your project. Factory tours are available by appointment — contact us to schedule yours.
