The Rig

Home for three years.

A Mercedes-Benz Sprinter 144 AWD, custom-built by Rossmonster — engineered to carry us from the Arctic to Patagonia and back.

Built for the long haul

One van, every climate

01

AWD drivetrain

A Mercedes-Benz Sprinter 144 AWD on BFG KO2 all-terrains — built to leave the pavement when the road runs out.

02

Off-grid power

A 990 Ah lithium bank, 400W of solar, and a 3000W Victron inverter to stay parked anywhere.

03

Four-season climate

Aqua Hot hydronic heat and heated floors against the cold; a 12V Nomadic A/C for the heat. Wool-insulated throughout.

04

Full galley

An induction cooktop, a DC fridge, and a butcherblock counter for the long stretches between towns.

05

Water & bath

A 30-gallon fresh-water system, an indoor hot-water shower, and a composting toilet.

06

Sleeps two, plus a garage

A fixed bed with FlareSpace bump-outs over a gear garage; the dinette converts to a second bed.

The build tour

A full walkthrough of the rig — inside and out.

Inside

A cabin, not a cargo box

The van galley — wood ceiling, kitchen counter, and patterned rug.
The bench seating and storage inside the van.

Light wood, a proper galley, and a bench to wait out the weather. The build is meant to be lived in for three years — comfortable enough to write home from, tough enough to get there.
