The PreRunner is not a 4 wheel drive vehicle. It is only rear wheel drive. It does have traction control and a limited slip differential. If you want a true off road Tacoma then get the 4 wheel drive model which is not the PreRunner.
It is basically a 4wheel drive Toyota Tacoma with only 2 wheel drive. All suspension components are identical to the 4WD version.
The prerunner means that it is a 2 wheel drive drive system but with the suspension and body of the 4 wheel drive. It has the lifted, tough look of a 4 wheel drive. I'm not sure what the letters in SR5 translate to, but it means a nice trim package, probably power doors and windows, CD player, AC.
