the hpi mt2 looks like a good truck and its 4x4. my friend has a savage and loves it. it doesn't break much, but he has snapped all the drive shafts at least once. the nitro stampede is also really durable. i had one and the only the only parts i had to replace were a stripped spur gear, servo arm and a drive shaft.(i did a wheely for about the 1000th time and the torque snapped it)
