Looking at getting a van for wfp, with 400l tank. Ideally I wanted something with seats in the back, for a few extra passengers. Found a Peugeot expert with 2 extra seats in back. Would it be ok to fix the tank in behind these seats, it does mean that the weight will be more over the rear axle than in the middle of the van, would this be a problem with the weight distribution and braking etc.

Any info on the ideal tank mounting location would be good, and on vans which I could achieve my idea of having some extra seats in the back.

Thanks
