Let me tell you a story ... everyone else who has heard me bore people with me extolling the Doblo 1.3 virtues pull up a sleeping bag.
Now - I am talking about my 1.3 Doblo with a 736kg payload bought new on a '56 plate back in late 2006 which is still going strong. So the newer 750 and 1000kg payload versions should be even better.
I bought this and fitted a DiY single operator (me) 400L system. I ran it until 2011 as such.
In 2011 my son - in - law joined me and we operated the same system with 2 x 25L barrels and a backpack (18L) for a month. So the payload was water 473L = 473kg. Plus me and Dan the Man = 673kg. Plus usual crap - I reckon we were on the limit.
For the next six months we towed a trailer with 200L tank and a reel in it! So the weight in the van dropped by about 100kg but the trailer added about 300kg with water, tank, pump and battery.
Then I got a bigger van with 1080kg payload and ran a 650L tank and two men.
But I kept the Doblo and Dan used it as a separate van with the 400L and occasional gutter gear.
Then Dan left in 2014 and rented some of my round but bought the Doblo.
He still runs the Doblo and is now occasionally using a second chap with a backpack and barrels! He is thinking of a new van but hasn't taken the plunge while he saves up lolly.
So at the present time the Doblo is coming up 12 years old from new, only on about 70K miles and still going strong.
Issues ...
Year two replaced under warranty starter motor packed up. Year eleven packed up again and replaced for about £120.00. (Lots of start stop work as a window cleaner)
Drivers door's window frame fractured at 3 years and cost about £120 at a garage to be repaired.
A side door jammed shut and had to be freed at 6 years. Cost about £80.00.
Clutch replaced at 6 years. Other than brakes, tyres, wipers, discs and pads - nothing.
No cambelt either. (Only on 1.3)
ALWAYS be meticulous about oil changes - small sump.
Word on the street is get a 1.3 or a 2.0 as the 1.6 has issues.
