I did close to 100,000klms in my work Amarok before handing it back and it spent almost half its life on unsealed roads and tracks with sometimes a trailer full of gear behind it as well with no problems at all. Towing the boat presented no problems either and with my son having the now superseded Navara, we were able to compare these two.. the result was the Amarok wiped the floor with the Navara, pulling power it left the Nissan for dead.. Fuel economy was heaps better with the Amarok also by about 20%... Resale on the Amarok was crap so now have a SV6 ute and it tows the boat better than both and originally wary with two wheel drive on some boat ramps soon discovered that my worries were unfounded..
