Might be a bit late with you asking a week ago…
I’ve got a SWB Transit crew – fits bikes in fully built. I put them in length ways (too long for the van) then bungee the handlebars to the roof (bike then fits a dream).
Best I had in there so far was 3 road bikes fully built and tipped up and two others in with front wheels off. Would have managed another one in there too. So 5 bikes, 5 people and all their cycling gear. All inside, all hidden away when we went to a cafe for breakfast. Perfect!
For slightly longer bikes worst case scenario would be front wheels off and 6 would fit.
Transit tends to do 35mpg giving around 600 miles per tank.
Reason I got the Tranny over the others – every Trafic/Vivaro etc I drove at the same age/mileage felt like gearbox or clutch were on their way out. Transit wasn’t quite as nice to drive but felt like it was still in one piece. Plus spares are so easy to get. Got a TDI one so chain driven, no complicated common rail technology.
And the biggest reason, I can sleep across the back seats, airbed fits in there and I can sleep full length, Trafic etc is slightly narrower and wasn’t as comfortable.
Had it over a year now and couldn’t be happier with it.
