I run them for work, fully loaded up all the time.
2005 to 2010, swb traffic. Sold it with 150k on the clock. The only spend outside of servicing and consumables was the engine management light came on at 130k. I spent half a day sitting in Renault in York who failed to find the problem so I took it to my local injection specialist who charged me £75 + vat to diagnose and fit a new solenoid on the turbo.
I also had a problem with a warranty recall for the power steering. The pump was changed and it took Leeds Renault 2 months to fix it. Cutting a long story short the new pump was faulty out of the box but they refused to accept that and tried many different things, even gave me the van back 4 times telling me it was fixed when it wasn't. Only got sorted when I complained to their head office.
2012 to present, lwb traffic high roof again fully loaded.
80k on the clock so far. 1 week after purchase the oil light came on. It took Renault Leeds a month to sort it, they replaced part of the loom and again it only got sorted because I got on to head office.
Since then it has been faultless and is a bit of a flying machine since I got it chipped.
I have a further fleet of 3 more, 1 traffic and 2 vivaros. The oldest is 2003 with 180k on the clock. The youngest is 2007 with 40k on the clock. One of them had an engine management problem but that was sorted under warenty the other 2 have not cost a single penny.
We also had a 2012 vivaro with a triptronic gearbox.
Crap. Cost a couple of grand to fix when it failed and was always problematical so I got shut.
