We want to buy a van-conversion campervan - does the Fiat Ducato have a reliable engine?

We're buying a new or nearly new van conversion-type campervan in the next year or two, most likely a 6m long Knaus. Most big brands like Knaus are based on the Fiat Ducato and, for 2020, Fiat has just introduced their Euro6 van engine now with AdBlue. What's the industry reliability of the current Fiat van engines (115/130/150bhp) and the likely reliability and perception of the new 2020 Euro's 6 engine range? Also, do you have any comments on Fiat vs the Mercedes equivalent that seem to be highly regarded by motorhome and campervan manufacturers and buyers even when sold at a premium price?

The majority of Fiat Ducato complaints (we hear about) are gearbox related. This seems to be a problem for many of the larger vans that have either the 2.3 130 or 3.0 157 engines with six-speed gearboxes. It seems that the old four-speed 'box was adapted to five-speed and six-speed but the extra gears are not very well supported and failures are common. Fiat has introduced a new nine-speed automatic to correct this reported issue, but it's too early to say if it's more reliable. We will likely know within the next 12 months and (if we receive any complaints) they'll be listed in the good/bad section of our Ducato review: vans.honestjohn.co.uk/van-reviews/fiat/ducato-2006/

For us, the Mercedes-Benz Sprinter is the best large van on the market: vans.honestjohn.co.uk/van-reviews/mercedes-benz/sp.../
