***Textual description***

This meticulously self-converted campervan is built with true off-grid capability and comfort in mind. Powered by a robust 280Ah LiFePO4 battery system, 600W of solar, and a 1000W Victron inverter/charger, it offers full energy independence backed by premium Victron components and shore power hook-up. The intelligent system is controlled via Venus OS with touchscreen and remote access.

I designed for long-term travel or full-time van life; it includes a powerful 4G internet setup with an external antenna and Huawei router, keeping you connected wherever you go. The custom-built kitchen features a real walnut veneer worktop, Dometic fridge/freezer, and Spinflo oven/hob/grill (we have never used the oven/grill portion, so as new!).

Enjoy year-round comfort with a Truma Combi 4E providing heating and hot water, a thermostatic shower, and a heated towel rail. Water is handled via high-capacity fresh and grey tanks, a Shurflo pump system, and proper fittings using John Guest components throughout.

A 38L underslung LPG tank fuels all appliances safely, with internal shut-off valves and drop-out vents. Ventilation is handled by Maxxfan and Skymaxx rooflights, plus custom magnetic screens and insulated window covers.

Sleep soundly on a full-width Nectar memory foam mattress over a curved slatted base, with USB-A and USB-C charging at hand. The van is fully insulated with rigid PIR panels, a vapour barrier, and even sealed trim clips to prevent water ingress—a detail many overlook.

Finished in high-quality Mylands paint and lined with durable flooring and carpeting, this van is a rare find: a thoughtfully executed, truly off-grid camper built with care, quality, and attention to detail.
