Just about to purchase my first motorhome. Looking at a Autotrail Arapaho. 2007 with 19k miles on the clock.(It's the facelift model 3.0 multijet) Lots of extras with the van. Now this is my concern, really like the van but it can only carry 4 seated travellers. I thought the whole idea of getting a 6 berth would be to take 4,5 people away. I have tried searching for retrofit for the rear facing seats but this is a grey area and not something that can be done after the initial manufacture. Or does anyone know if it can be done. Is there any potential problems or things I need to be looking out for. The only things I noticed was the shelving in the fridge, freezer where rusting. Can new shelves be obtained. Any advice greatly received thank you.
