Three years, one cat, and a 1978 Dodge Commander she rebuilt with her own hands.
Jessy Muller bought her motorhome off Craigslist for $1,900 — a 175-square-foot rig with a rotted-out rear end that most people would have walked away from. Instead, she spent more than a year gutting and rebuilding the structural walls and ceiling before she ever turned the key and drove off in 2017. Three years later, she’s still on the road with her cat, Moonchi, running a fully off-grid home that she built almost entirely by herself.
- Muller paid $1,900 for the 40-year-old, 175-square-foot 1978 Dodge Commander and spent over a year repairing severe water damage to the walls and ceiling before living in it full-time.
- She converted the rig off-grid with a solar power system, a remodeled bathroom featuring a composting toilet and shower, a queen-size bedroom, and a full kitchen with an oven range and full-size refrigerator.
- With no prior mechanical training, she has handled major repairs herself, including pulling and reinstalling the radiator and replacing all of the coolant components.
From Water-Damaged Shell to Off-Grid Home
When Muller found the Commander, the back end had taken on so much water that the interior structure was compromised — not a cosmetic problem, but a framing one. Rather than patch over it, she tore out the damaged sections and rebuilt the walls and ceiling from scratch, a project that ate up more than a year before the RV was road-ready. That timeline alone separates her build from a typical weekend renovation; it was closer to a ground-up reconstruction of a 40-year-old vehicle.
Once the bones were solid, she turned to systems that would let her live independently of campgrounds and shore power. A solar setup now handles her electrical needs on public land, which is central to how she travels: find a spot to boondock, stay a while, and avoid burning fuel chasing the next hookup. It’s the same off-grid logic that shows up in builds like the self-built, off-grid floating home some tiny-living owners have taken to the water instead of the highway.
The Interior Overhaul
Inside, Muller prioritized the same rooms anyone renovating a house would: bathroom, bedroom, kitchen. She pulled the RV’s original plumbing and installed a composting toilet, added a shower, and built in extra storage where none existed before. The rear bedroom got a queen-size bed — a rare luxury in 175 square feet — and the kitchen was outfitted with an oven range and a full-size refrigerator rather than the mini-fridge setups common in most van builds.
Space efficiency mattered as much as comfort. In the living and dining area, she reconfigured the layout around a swivel tray table designed to save floor space, letting the same footprint serve as a workspace, dining spot, or open floor depending on the moment.
Becoming Her Own Mechanic
Muller had no formal mechanical background before she hit the road, but a 40-year-old vehicle doesn’t leave much choice. She’s handled everything from routine maintenance to pulling and repairing the radiator herself, then replacing all of the coolant-related components — the kind of job that would run hundreds of dollars at a shop, done solo on the side of the road or in a driveway.
A $1,900 Craigslist buy, a year rebuilding rotted walls and ceiling, and a radiator she pulled and reinstalled herself — Muller’s Commander runs on skills she didn’t have when she started.
Funding the Nomad Life
Muller supports herself through remote creative work, one-on-one phone coaching for people considering the same lifestyle, and her digital guide, Vanlife: Your Guide To Becoming a Modern Nomad. She documents the build and her travels through her blog, A Girl and Her Commander, and on Instagram as @slowroamer. Her approach mirrors what other full-time travelers have found chasing independence off the beaten path, whether that’s a solo kayak trip down the Frio River or a multi-day trek alone through backcountry trail.
Her philosophy, as she tells it, comes down to self-reliance and pace: slow down, spend less on fuel, spend more time immersed in the landscape, and don’t let fear be the reason a plan never leaves the driveway.
