A quick google search reveals.... nothing much of interest. I suspect you have a big-box-store BSO which is physically identical to many other bikes, but perhaps with different stickers. There's nothing wrong with that, as long as the bike gets used.
Unfortunately Overlander and Outback are two models of a vehicle, which seems to clutter search results.
The head tube badge seems to say OB or DB, but I don't recognise it.
The bike's frame would be called a "rigid MTB" and probably dates from the 90s. The typefaces in the logos also suggest that.
The bike's fork is rotated 180 degrees at the moment, probably partialy because its wedged in the backseat of a car. Get it out, air up the tyres, give it a quick M check for safety, and give it a ride.
Some light lubrication may be required if its been sitting for a while, but that bike looks eminently rideable.
