i bought a 1.9 jtd sx doblo van about a month back as it was the best combo of space, fuel economy, engine power and cost. i took the bulkhead out of mine and with the seats right forward someone up to 6ft can lie flat in the back if you ever wanted to kip in it. i have slept in mine with all the kit, the bike and a pressure washer with room to spare. it is high enough to have a bit of room to get changed in too.
the 1.9 jtd has plenty of power and as a positive compared to my diesel car will happily sit at 2000rpm without feeling like it needs to be changed down a gear. average mpg is 56.5. my brother has the multijet version 105bh which is euro4 emissions and hence £125 a year tax mk2 06 onwards. mine is the unijet 100bhp version euro3 emissions mk1 £200 a year tax. from all accounts avoid the 1.9d non turbo like the plague. unijet and multijet are both common rail engine can be remapped etc if you wanted.
obviously it looks retarded and the seating position is an acquired taste but you can’t have everything can you? a vauxhall combo is worth a look as the seats are the same as the corsa hatch so the seat back tilts forward if you needed to kip in the back at races/roadtrips whatever, long wheelbase ford transit connect worth a look but are dearer by some way, older engine design and you have to pay extra for electrics lx trim. sx model doblo comes with electric windows and central locking as standard. sorry for the stream of conscience style. any questions just shout.
