The expedition vehicle specialists at Action Mobil are filling out their Pure lineup with an even meaner all-terrain motorhome. The Mercedes Zetros base brings serious turbo-diesel muscle, plenty of height and an off-road-specific driveline. Drop a 16.4-foot (5-m) living module on its back, and the Zetros becomes the Action Mobil Pure 5000 Zetros, an ultra-rugged expedition motorhome built to climb, crawl, splash and maneuver all around the world, spending blissful nights below the the starry, wide-open sky.
When you're looking for a rugged off-road truck to serve as the basis of your world-conquering expedition rig, it's hard to go wrong with a vehicle that can rightfully call itself the Unimog's bigger, stronger brother. That's the Zetros. Action Mobil has built Zetros expedition trucks before, but the Pure 5000 Zetros represents the first time it's married the rugged Zetros 1833 A 4x4 with the type of compact Pure motorhome box it usually bolts to a MAN chassis. The MAN trucks aren't exactly fragile snowflakes, but the Zetros' big pronounced nose, cut chin and high, sturdy front wheel arches leave the Pure series looking more powerful than ever.
Designed to perform some of the world's most difficult jobs in its hardest-to-reach corners, the two-axle Zetros 1833 comes powered by a 322-hp 7.2-liter six-cylinder turbo-diesel offering up to 959 lb-ft of torque permanently split between the front and rear axles. The truck also includes three switchable mechanical differential locks and a 1.69 off-road gear ratio. Beyond off-road adventuring, the Zetros spends its time working mines, battling raging forest fires, responding to emergencies and reworking landscapes.
Needless to say, the Zetros makes an incredibly capable foundation for any specialized off-road vehicle. By dropping on the Pure motorhome box, Action Mobil works that foundation into a "luxury expedition truck for extreme terrain."
The Pure 5000's interior layout is straightforward but nicely equipped, starting in the back with a raised fixed bed behind a convertible dinette with U-shaped bench seating. Just ahead of the dining area on the driver's side, the kitchen houses a four-burner induction cooktop, electric oven with steaming capabilities, dishwasher, fridge and freezer. The sink is set into granite countertop.
At the front of the living area, the dry bath is split into a shower room in the small central hallway just behind the driver cab pass-through door and a separate toilet compartment to the side.
Not surprisingly, the Pure 5000 Zetros rolls out of the garage much better prepared than the average motorhome for roaming off-grid for long periods of time. It carries dual 300-L diesel tanks, a 460-L fresh water tank, a 140-L gray water tank, a 540-Ah lithium battery bank, and a 1.1-kW solar power system. The spec sheets we've seen don't mention the type of fancy A/V equipment seen on other Action Mobils, but they do list diesel/electric heating capabilities, air conditioning and a washer/dryer.
Action Mobil announced the Zetros-based Pure 5000 last month, showing a polished model with global exterior graphics standing strong against the frigid Siberian backdrop. We also saw an earlier iteration of the truck at the 2018 Abenteuer & Allrad show.
Unfortunately, there's no pricing information on the Pure 5000 Zetros product page, in Action Mobil's December announcement, or on the specs sticker that was slapped on the side of the show truck. We do know that when Action Mobil first launched its MAN-based Pure trucks in 2015, prices started at €265,000 (approx. US$302,000, as converted today), so you can be sure the Pure 5000 Zetros is among the more expensive fresh-built Mercedes vehicles a private citizen can buy.
