New van Discussion ThreadNew van Electrical Advice

I'm doing my usual nonsense by obsessing about something months in advance. 😀
I'm due to change my van in January.
I have a VW Transporter that I am more than happy with but it's a lease and has to go.

Does anyone have the new Ford Transit Custom?
If so what are your thoughts?
