The build, by the numbers.

This 12′x31′x12′ Regular RV Carport features two gable ends and two extra side panels, constructed with a durable 14-gauge galvanized steel frame and 29-gauge steel panels.

Nothing is framed for drive-in access as listed, so an opening or overhead door is sized at quote. Buyers most often order a 12′x31′x12′ rv carport for a fifth-wheel and tow vehicle cover side-by-side. It also gets ordered for long-stay seasonal rv parking.

What's it for

Same shell, very different jobs.

A 12′x31′ gets specified differently depending on what goes in it — door placement, openings, leg height, whether it closes in. Tell us the job and we'll spec it to that instead of handing you a blank form.

Questions

Good to know.

A specialist can walk you through this exact build over the phone in a few minutes.

No concrete required. A 12′ x 31′ x 12′ cover anchors to concrete, asphalt or compacted ground, and the right anchors for whichever you have are included. What matters is that the 12′ x 31′ area is level and clear when the crew arrives.

Eave height. On a 12′ x 31′ x 12′ that means 12′ of straight wall before the roof starts to pitch up, so usable height at the walls is 12′ and the center is taller. Measure your equipment against the eave figure if it sits near a sidewall.

It can be. Sides, ends or both can be panelled on a 12′ x 31′ x 12′, and that decision belongs on the quote rather than afterwards — panels fitted at the factory land better and cost less than a retrofit.

Delivery and professional installation are both in it — the crew sets the 12′ x 31′ x 12′ on your site. What it does not cover is getting that site ready: leveling, and the concrete if you are pouring a pad. That happens before the crew arrives, by you or a local contractor. Treat $4,025 as the starting figure; options and your county's wind and snow certification move it.

Rust-through on the frame runs 20 years. Workmanship on the install runs 30 days. They are deliberately different lengths because they cover different risks — the steel of this 12′ x 31′ x 12′ degrading, versus how it went together on your site.

The 12′ x 31′ x 12′ shown here is one point on a range, not a fixed product. Width adjusts in 2-foot increments, length in 5-foot increments, leg height by the foot — so if you need a few more feet of 31′, that is a re-price rather than a different building.

Two different parts. The frame is the tubing carrying the load of this 12′ x 31′ x 12′ — 14-gauge galvanized steel. The panels are the skin screwed to it, 29-gauge steel. Lower gauge number means thicker steel, so the frame is always the heavier of the two. Compare frame to frame across quotes; that is the number that decides how a building stands up.

We are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
