I have been looking at various motorhome and have found a really nice one that has recently been refurbished. The downside to this refurb is they have removed the forward and rear facing dining area and has 2 long side facing seats that fold down into a large double bed. There is now no belted passenger seats in the rear. So my question is, would it be possible to remove the single fron passenger seat and replace this with a double belted front seat. The motorhome is based on a 1996 fiat ducato
