Carawagon.

R. J. Searle Ltd of Sunbury-on-Thames were boatbuilders first, which shows in the Carawagon: the roof that defines it is a flexible aluminium sheet on marine plywood formers, lying flat in transit and springing into a full-length arch when raised, with hinged end panels that fold inside. Raised, it gives 6 ft 2 in of headroom down the whole vehicle — enough to stand and cook in — and a short roof rack usually sits above the cab. Not every Carawagon had it: some were built with a fixed roof and a full-length rack instead.

Searle worked across the Land Rover range from the early 1960s to the mid-1980s. The 109-inch five-door Station Wagon was the mainstay, the 109 three-door was common, and the 88 was offered but rarely taken; a handful of two-door Range Rovers were converted too. The body modifications were approved by Land Rover: the rear side benches were reworked, the wheel wells cut into for storage, and on three-door vehicles the bulkhead behind the front seats was removed to open the interior end to end.

Inside, the standard arrangement was either twin opposing rear benches converting to two beds with a removable table between them, or a single bench on the left facing a cabinet on the right. Both came with a storage cupboard, a sink fed by hand or foot pump from a nine-gallon tank, a two-burner stove and grill usually mounted inside the rear door and folded away for travel, and fluorescent lamps. Folding front seats made another double, and four-berth cars added two roll-out hammock bunks. The options list ran to a dual-fuel refrigerator, dual batteries, a fuel-fired heater, air conditioning, fly screens, a portable toilet, and a rear awning on an extending slide-out frame. Everything was built to order, so no two are quite alike, and Searle sold them under model names — the 109 'Ultimate', the two-berth 'Continental', the 'Ulysses' on the 110, and the 'Safari 88'.

Carawagons were bought to be used hard. Most of the survivors have expedition histories, which is the main reason so few remain from a run of roughly 2,500. A 1968 Series IIA 109 with the 2.6-litre straight-six went from the Solihull production line straight to Searle for conversion; a 1972 Series III 109 four-berth in Pastel Green, LPD 606K, survives with its original Carawagon order correspondence and itemised invoice alongside a fuel log its first owner kept for 37 years and 155,000 miles, averaging 18.71 mpg. The firm later traded as Carawagon International.

The Ministry of Defence ordered around 34 as tactical command and control vehicles, which became the separate Military Carawagon: same elevating roof, but with blackout curtains, dark glass, a single side window and a camouflage-net rack over the cab. Searle's chief rival in the Land Rover camper trade was Martin Walter of Folkestone, whose Dormobile took the same idea in a different direction with its side-hinged elevating roof.
