Because of their traditional full-frame construction and standard rear-drive layout, Safaris are most adept at heavy hauling and burly trailer towing. This is one of the very few minivans (GMC calls it a midsize) on the market that offers over 6,000 pounds of trailering capacity making it suitable for fleet use. The Cargo Van model is offered with a stripped-out interior ready for upfitting into a workhorse service van -- complete with tool racks or parts bins. Not everyone will relish the truck-like ride over harsh road surfaces, but it's not bad when the highway smoothes out. Don't expect top-notch fuel mileage, though, despite a continually improved powertrain. All-wheel drive is optional providing superior traction for companies who can't have their trucks stranded when the weather gets ugly.

GM's 4300 Vortec V6 is standard, sporting more durable camshaft bearings, a lighter starter that requires less current from the battery to crank the engine and a new, more advanced powertrain control module. The 4.3-liter sends 190 horsepower and a healthy 250 foot-pounds of torque to an electronically controlled, four-speed automatic overdrive transmission, equipped with a tow-haul mode for improved performance under loads. Long-life engine coolant and spark plugs help keep maintenance costs to a minimum.

New for this year is a Safari cargo van that meets national low-emission vehicle standards. Companies looking to reduce the environmental impact of their numerous fleet trucks can now do so without losing the versatility and toughness that Safari provides. Dual airbags are housed in an artfully styled dashboard, and four-wheel disc/drum antilock brakes are standard. So are features such as speed-sensitive power steering, delayed interior lighting, overhead reading lamps, various built-in cupholders and storage bins, and three power outlets.

Insiders say that Safari's days (and those of its Chevy Astro sister) are numbered. But for now, whether your choice is simple rear-drive or full-time all-wheel drive, Safaris are still the smart choice for anyone looking for a tough minivan that doesn't squirm when faced with some heavy-duty hauling and towing.
