Hi Christine,
It's the front seat arrangement I need.
Mine has the rear bench seats, which pull out to make the double, with the full length seat back on one side dropping down horizontal to fill the space on one side.
The seat back on the other side is made up of two smaller ones. I understand they form part of the length of the bed using the front seats.
It's all a bit difficult without pictures, but mine is filled with stuff at the moment so can't get in to take pictures.
Of course, I could be wrong, and the front seats just fold like any other Carawagon (lift out squab, fold the seat back down and put squab on top), but I'm sure I've seen a picture somewhere where the small seat backs from one of the bench seats fills the gap between the front seats and the dash, otherwise I think the bed might be a bit short (just measured at a total of 60" long)
With mine came some short lengths of square tubing (5 shown here but I found another):

I was thinking they might have something to do with extending the bed at the front
Re. the table, you should have 3 leg screw fittings. Mine has 5, but it looks like someone has added another two so the table can be used outside.
Leg storage:
Table set up for outside:
Table set up for inside:
You should have a section on the back of the bulkhead with two holes:
With the three legs fitted, two of the legs drop into those holes. The other end of the table has one leg so you can get past it to sit down.
Hope that helps with the table - when I start to restore this one I'll have another play with the bed arrangement.
Cheers,
Robin.
