Off road

I'm looking for advice on any dual-cab 4x4 ute. I'm currently looking at a 2012 Ford Ranger with 200,000kms or a 2009 Hilux with similar kilometres. I would like your opinion on what I should look at for a good reliable dual-cab ute for a bit of towing (two tonnes) and 10kms of dirt road everyday. I read the Rangers had an engine problem so I'm a bit worried about that but like the sound of the 3.2-litre engine for towing.

I'm in the market for a new/used car and was thinking of getting a Toyota Yaris but was wondering if it's suitable for the occasional dirt road adventure, in particular, the Oodnadatta Track via Marree. In reality 99 per cent of our driving is in the Adelaide Hills with a trip to Mount Gambier once a year. We are interested in down-sizing and fuel efficiency.

Can you please tell me the height of the running board on a standard GLX Toyota 200 series from the ground to the top of step?
