The Install

From Driveway to Camp in Under an Hour

No carpentry. No special tools. No professional installer needed. Here is exactly how it works.

🎬

Install video coming soon. Check back or contact us to see it first.

01

Prepare Your Van Floor

A flat plywood base (or factory-installed floor) is all you need. Some newer vans have a solid floor already installed.

02

Position on the Sled

Place the kit on the two included installation sleds behind your van. No lifting required for this step.

03

Slide Into the Van

Push the two kit pieces into the van interior. Having a second person makes this faster, but it is manageable solo.

04

Expand and Secure

The kit expands outward to the van walls for a flush fit. Secure with the included mounting hardware.

05

Connect and Go

Plug in the electrical connection, fill your water tanks, and you are ready. From unboxing to camping in under an hour.

The Process

How Ordering Works

Every kit is made to order. Here is exactly what to expect from deposit to driveway.

1

Place Your $5,000 Deposit

Your deposit confirms your van model and add-on selections and starts the production queue. We will confirm receipt and your expected build window within one business day.

2

We Build Your Kit

Production typically takes 6 to 12 weeks. Your kit is built to order, inspected, and carefully packed for ground freight shipping.

3

Pay Balance at Ship

The remaining balance is due when your kit completes production and is ready to ship. We will notify you in advance so there are no surprises.

4

Delivery to Your Driveway

Free ground freight to the lower 48 states. Typical transit time is 1 to 2 weeks. You will receive tracking information as soon as your kit ships.

Common Questions

FAQ

Do I need to modify my van before the kit arrives?

+

The only preparation needed is a flat floor surface inside your van. This can be as simple as a cut-to-fit plywood sheet. Some newer van models come with a solid factory floor that works perfectly without any modification. We recommend adding your own van wall insulation before delivery if you want additional thermal performance.

Can I install the kit by myself?

+

The kit is designed for solo install. Each of the two pieces weighs approximately 300 to 500 lbs, so having a second person for the push-in step makes it easier and faster. Once inside the van, everything else is straightforward. If you are near Portland, OR, we also offer professional installation for an additional fee.

Does the kit include a heating system?

+

The kit does not include an internal heater, but it is designed to work with portable electric heaters plugged into the optional EcoFlow battery or your van's power system. The high-density insulation and air gap between the kit walls and the van's metal body means the interior stays noticeably warmer than outside. Most customers find a small electric heater more than sufficient.

Can the kit be removed from the van?

+

Yes. The kit is not permanently attached to the van structure. It is secured with mounting hardware and can be removed if needed. This also means the van can be returned to its original cargo configuration if your needs change.

What happens after I place the deposit?

+

We confirm your order and add-on selections within one business day and add you to the production queue. You will receive updates at key build milestones. When production is complete, we contact you for the remaining balance before shipping. Ground freight typically takes 1 to 2 weeks after it ships.

What if I have a question after delivery?

+

Every kit comes with a detailed video walkthrough of all systems and features. Our team is available by email and phone for any questions that come up after delivery. We are a small team and you will get a direct answer, not a support ticket queue.

Can I customize the layout or finishes?

+

The core layout is fixed, but we offer a range of finish options and add-ons. If you have a specific customization in mind that goes beyond the standard options, contact us before placing your deposit and we will let you know what is possible.

Ready to Transform Your Van?

A $5,000 deposit starts production. The rest is due when your kit is finished and ready to ship. No surprises, no long waits, no guesswork.
