Storyopen TrailHome 20 XL Extended Single Module Mobile Home — Expanded Living Edition

The Storyopen TrailHome 20 XL Extended Single Module Mobile Home takes the proven TrailHome 20 platform and expands it to the maximum legal road-transport dimension of 4.2 metres width — delivered as a wide-load movement under standard abnormal load permit — to deliver 22 square metres of floor area with a layout that accommodates a genuinely separate bedroom space alongside a full open-plan kitchen-living area, without requiring the planning complexity or utility infrastructure of a two-module home. The TrailHome 20 XL is the solution for buyers who need more than a studio-format single module but want to avoid the additional cost, complexity, and site preparation requirements of a twin-unit installation.

The expanded 4.2-metre width module delivers a structural SIP panel envelope achieving a U-value of 0.17 W/m²K across the full external surface, with the additional width allowing a bedroom partition that provides genuine acoustic and visual privacy between the sleeping and living zones — a spatial quality distinction that the standard 3.6-metre-wide TrailHome 20 cannot achieve within its narrower floor plan geometry. The kitchen is fitted with a 2,100mm run of base and wall units with a stainless steel sink, four-burner hob, under-counter refrigerator, and a 45-litre electric oven. The bathroom delivers a full-size shower enclosure, WC, vanity wash basin, and a heated towel rail.

The electrical system is pre-wired to 18th Edition standards with a 16-way consumer unit, smart meter interface, and a 1,000Wh lithium battery system with shore power and solar charge input. The water system includes a 250-litre freshwater tank, 12V pressure pump, UV sterilisation, and a 200-litre wastewater holding tank — a complete standalone water system operational without mains connection from the day of delivery.

Storyopen delivers the TrailHome 20 XL on a specialist wide-load vehicle with a dedicated abnormal load pilot car as required by route survey. A full route survey is conducted by Storyopen’s logistics team before delivery confirmation to ensure that the wide-load movement to the specified site address is achievable under current road network constraints.
