The body of the the crafter is just a merc sprinter with different headlights and all seem to rust, dunno what engine they run though,
I considered this van but went for the renault master,this fits 1000 litre tank,Sealey 200m hose reel mounted at side door, Gutter vac,Generator,Pressure washer,whirlaway & triple ladders mounted inside.
The one benefit the master has over the crafter and transit is the low load height,I also have a t330 swb transit with side twin loaders, which will have the same kit but with a 650 litre upright, the load height of this van is nearly a foot higher than the master
