I have the Fiat Fiorino with a 350 in it , it handles it well but does sit low at the start of the day .
With regard to poles , I have the metal frame bulkhead and I carry an SLX18 , Xtreme 25 and an SLX 35 , they just fit but do go all the way into the cab but don’t get in the way.
If I was buying again though I would go Doblo for that little bit more
