The question we hear most from people considering a DIY kit is not about tools or skills — it is "how long will this actually take me?" So here is a week-by-week diary of a typical kit build on a 144" chassis, done the way most customers really do it: evenings and weekends, with a day job in the way.
Week 1: The unglamorous foundation
Days one and two disappear into cleaning, rust-checking, and sound-deadening panels — tedious, transformative, and completely invisible in the finished van. The rest of the week goes to insulation and the subfloor. Nothing looks like a camper yet, but closing the doors already sounds different: a solid thunk instead of a tin-can rattle.
Week 2: The box becomes a room
Wall and ceiling paneling is the emotional turning point of every build. The roof fan goes in first — one deep breath before cutting a hole in a perfectly good roof, then twenty minutes of careful jigsaw work and it is done. By Sunday night there is wood overhead and the van has stopped being a vehicle and started being a place.
Week 3: Cabinetry week
This is where the kit approach pays for itself. Every cabinet arrives CNC-cut, pre-drilled, and labeled; the week is assembly and fitting rather than fabrication. The galley, overhead cabinets, and bed platform go together with a drill and patience. One evening is lost to a cabinet installed six inches too far forward — the instructions were right, the builder was confident. It happens.
Week 4: Power, water, and the finish line
The electrical package lands mid-week: power station mounted, fan and lights connected, fridge cold by Thursday. Water is a weekend job — tank, pump, sink. The last days go to trim, latches, and the mattress. Thirty days after the empty van rolled in, it rolls out for a shakedown weekend in the mountains.
Nothing about a kit build requires talent. It requires showing up for thirty evenings in a row — the kit's job is to make sure every one of those evenings ends with visible progress.
What we would tell every first-time builder
- Double every time estimate that involves the words "quick" or "just."
- Do the cardboard mockup week. (See our layout-mistakes guide.)
- Order the fan, windows, and electrical early — hardware lead times, not skill, set most schedules.
- Take photos of every wall before it closes up. Future-you will need them.
