Yes I have a 08 plate H2 l2, so the long wheelbase high top versions and its bloody brilliant.
Currently have a separate boot space for the bikes whitch easily takes 2 bikes, spare wheels, dirt worker, tool box and lots of other bits. Then inside I have it fully insulated and carpeted. 3/4 rock and roll bed and a large cupboard that takes up a quarter of the roof space that we stash all the camping gear in. There is then the usual leisure battery, LED lights and sockets and a diesel night heater under the passenger chairs.
We have friends who all have the usual Transporters and despite them not liking to admit it the Citroen really is perfect size. My self and my girlfriend have had over 28 nights away so far this summer with more to come and we love it.
