Those Fiat/Pug/Citroen vans are really nice. They are the base of about 75% of campers on the road. I have not driven a standard van, only a coachbuilt camper version, but it was a nice drive.The previous versions, C25 have lasted well. Still see quite a lot of them around.
Mercedes Sprinters drive so well. The 311Cdi with the 2.1 engine. Rust is a big problem, but they really are such a nice place to cover distance. Had a temp job 22yrs ago for a few months where I was using one daily. I was so impressed with how it drove. Prior to that, bay window VW camper was my van experience, and whilst nice, they are slow. The Sprinter was a luxury van.
Remember the Renaults from the 70/80's. Such cool vans.
Citroen H van........sadly they are all being turned into naff catering vans these days, but oh so cool.
