Have an '12 CI Carioca 707 (identical to the rollerteam 707 afaik - the CI forum is even slower than here so will try this forum first) with the overcab bed on a slatted base. Can someone else who has a similar model Rollerteam or CI advise how far under the mattress the slatted base extends? On ours we have a shaped mattress - folds to allow the overcab bed to raise then tapers towards the front of the vehicle. The slatted base is in two sections underneath and stretches 2/3 of the way across. Not sure if this is intended or if there is a third slatted section missing. Seems there might possibly be given the matress is not flat, being an obvious dip at the end of the slats. Google hasn't helped. Be useful if someone with a similar model could advise! Failing this will have to take a look at similar in a dealership.
