Two other things that interested us in convos, when we were first looking at vans:
1. Possibility of having a LWB. Adds (from memory) a very useful 13 inches. However, due to the limitations of seat fixing point positions in the LWB T5, it was a problem to have that space added at the back, ie for extra gear storage, rather than in the living area.
2. Possibility of a high-top. Swings and roundabouts vs pop-top of course, but we could see the benefit of hi-top for certain modes of touring, especially winter.
But after we did the sums, choosing to go Cali became quite easy for us just on the finances.
