I use a 2011 Isuzu Rodeo Denver Max 2.5 TD as both my work vehicle and for towing our caravan, it does both jobs fantastically !!!!!
I disagree that this is the model to avoid, it has towed our caravan around the UK and France without any issue whatsoever and although the ride maybe a bit firmer than most vehicles I have not felt uncomfortable even after doing a long distance drive.
Mine came with stereo CD / Radio / Bluetooth fitted as standard as well as a truckman hard top for the rear load area - perfect for loads of equipment OR our two border collies !!!
Cost wise, apart from it being serviced on a regular basis, I have had to buy 2 new front tyres & a set of front brake pads on a vehicle that has just topped 76,000 miles.
I average 33mpg towing caravan and can do over 350 miles on a tank of fuel.
They may not be for everybody but as they say in a well known advert "it does exactly what it says on the tin" and more.
When the time comes to replace it I won't be looking past the Isuzu D-Max, and that's only because the Rodeo is no longer available .
