i have mine mounted to the van floor so there always connected to the system, i have a static ro and di with quick transfer pump so no need for any ins and outs and no need for the reels to leave the van, there has been debates about this before but i personally think its what suits each person best, but i definatly recommend having the reels on the inside but have the microbore run under the van doors...works perfectly, don't know if it will on all vans though but i presume it would as they will all have rubber surrounds
