I have a few vans and one is a Peugeot partner on a 14 plate and I can honestly say I wish I never got it. Vans alright, good on fuel etc but it useless for carrying tools, stock, steps, etc. It is just to small, the back gets tidied up every week then when you look for something that you know is on the bottom the whole van gets turned upside down and stays like it for the rest of the week lol.
I also have a transit custom that IMO is brilliant and just the right size, plenty of room in the back for what I need, 3 seats, easy enough to still get in to car parks etc. I think MWB vans are about the right size for an electricians needs and personally wouldn't get another small van again.
