The taxman has accidentally invented a new kind of pick-up: one with four doors, two seats, an open load bed and a second cargo area where your passengers used to complain about the legroom. KGM calls it the Musso Commercial. Tradespeople may simply call it useful.
Starting at £33,980 excluding VAT, the Commercial takes KGM’s familiar double-cab truck and removes the rear bench. In its place sits a secure, van-style compartment separated from the front seats by a full-height mesh bulkhead. There is a heavy-duty rubber mat on the floor and security mesh over the rear windows. Dirty materials can live in the bed; expensive tools can hide indoors. It is a practical answer born from a gloriously impractical corner of British taxation.
A truck redesigned by an HMRC manual
Since April 2025, HMRC has expected most double-cab pick-ups to be treated as cars for Benefit-in-Kind and capital-allowance purposes. The old shortcut, under which a payload of at least one tonne generally secured van treatment, no longer decides those questions. HMRC now looks at the vehicle as a whole and asks what it is primarily suited to do.
A normal double-cab has a second row of seats and carries people as readily as equipment, so it usually lands on the car side of that test. KGM’s solution is deliciously literal: remove the people bit. The company says the dedicated two-seat conversion retains standard commercial Benefit-in-Kind treatment and eligibility for a 100 per cent write-down allowance.
Tax is never a thrilling reason to engineer a vehicle, but it often produces fascinating machinery. The Musso Commercial is less a lifestyle accessory and more a rolling argument with a spreadsheet. Crucially, the argument has some practical merit after the accountant goes home.
Two load spaces beat one muddy compromise
Pick-up beds are superb for awkward, filthy or tall loads. They are less convincing when the cargo is an expensive drill, diagnostic equipment or anything that dislikes rain and opportunistic fingers. Converting the rear cabin gives owners a lockable, weatherproof area without sacrificing the external bed. Think of it as a toolbox with its own doors, windows and seat-belt mounting points from a former life.
KGM offers the treatment on Rebel and Saracen versions. The £33,980 Rebel Commercial uses the six-speed automatic gearbox; Saracen Commercial begins at £36,780 excluding VAT. KGM’s current price list puts each conversion at the same cost as the equivalent automatic five-seat model, so businesses are not charged extra for surrendering three seats. That is refreshingly sensible. Paying more to receive less furniture would have been a little too on-brand for modern motoring.
The compromise is obvious. A crew cannot travel in it, and the exterior still occupies the road space of a double-cab. Anyone regularly carrying colleagues will find a conventional van or another arrangement more useful. But a sole trader who travels with tools rather than teammates gets separation, security and a proper pick-up bed in one vehicle.
Old-school hardware survives the conversion
The Musso Commercial keeps the 2.2-litre diesel engine, selectable four-wheel drive and low-range gearing. KGM quotes a 3.5-tonne towing limit for the automatic Musso and says it can carry more than a tonne while towing. This is traditional working-truck territory: no terrain-themed graphics pretending to be capability, just mechanical hardware for slippery sites and heavy trailers.
It is not stripped bare inside, either. Rebel includes heated front seats, a reversing camera and a 12.3-inch screen with navigation, Apple CarPlay and Android Auto. Saracen adds richer equipment, including dual-zone climate control and powered, ventilated front seats. Ventilated leather in a tax-driven two-seat work truck is wonderfully extravagant, like fitting a velvet handle to a sledgehammer.
KGM covers the Musso for five years or 100,000 miles. That matters more here than fashionable trim names, because commercial vehicles earn their keep by appearing every morning and getting on with the job.
Clever fix or regulatory farce?
There is something absurd about manufacturing a roomy rear cabin, fitting doors and windows, then deleting the seats to satisfy a tax distinction. A purpose-built single-cab might be neater. Yet the existing shell gives KGM a quick route to market and gives owners protected storage that many ordinary pick-ups lack.
The Musso Commercial therefore deserves more than a snigger at its missing bench. It turns a rule change into a genuinely useful layout and does so without adding a conversion premium. Britain’s tax code may have supplied the brief, but KGM remembered the person who actually has to carry the tools.
