Here is a pic of the set up. The chairs look a bit lumpy and I'm not sure if we put the backs down too much?? Mmmmmm.
We liked the width from having the whole van but the contours of the chairs needed addressing. We originally used a thermarest with cushions in the gaps then 2" memory foam topper on that. We have advised by the woman from Highland Campervans to put wedges of cushion foam in the gaps (2" slopping to 1" or thereby) then a thermarest on top.
The other option for more comfort might be to use the big square jigsaw foam mats things that you would use on a shed/workshop floor sort of idea and make a strip of 3 or 4 then use the thermarest / inflatable mattress (still with the foam wedge in the gaps). Takes up next to no room and easy to pack up etc. This is what we are going to try at the end of the month when we go away again.
In the kitchen unit we have a sink with waste container underneath and a 2 ring hob with gas bottle underneath. To be honest, we didnt use either this last week away as we were in a nice site, cooked in the awning (Khyam Tourer to be highly recommended) and washed up at the facilities too. We have a water pump but had no intentions of using it either. From mem ory the unit is about 37" long and sits right at the back door. We have 2 electric sockets on the end near the sliding door. Access to the rear 12v socket is by the rear of the cupboard so we needed to open the cupboard door but that was not a problem at all. I also used a 12v extension plus we have an inverter thing so that 12v appliances can work on mains electric.
I will try to get better pics tonight but I am at work just now so limited as to what I can do.
The gull wing seat has no been removed so ig nore it in the picture
Will get back to you.
