Doug,
the only dilemma I have with mine is exactly what you speak of the "fridge", I have a 40lt in my tug for our general fridge stuff, and I have 21lt as a freezer located on the storage side of the CT, I have fitted up the sockets etc to run it from that location.
The problem I have, is I don't have enough room for any drinks, on our last trip I took with me on the rack of the CT a 50lt ice box which had our drinks in it, I guess its not a real problem, more an inconvenience I suppose.
The obvious prob with the fridge in the storage side is you loose some space, now as you alluded to Adventure do a fridge/storage box for the front of the CT, (there interchangeable) which can house a 60lt engel, which is ideal, except you have to cough up your first born child to get it (very expensive).
I' am currently exploring the option of a 3rd fridge, yes that's right 3rd fridge,

for carrying our drinks, i'm undecided whether ill go for another 21lt, or maybe the 32lt which has a bit more room for not only drinks but other food stuffs that spill over from my car fridge, the costs need to balanced out against all options. ill loose some space, but gain some convenience.
I guess with all CT's you have to juggle were certain things go in your set up, I like things set up in an a way so I can get at them when needed, like most people.
If I had the $$$ available I would prob buy the front fridge box which would go along way to easing the only drama I have with the CT, other then that its awesome.
The one thing you need to have a real good look at is the canvas, whilst the canvas is aussie made, its defo not 15oz canvas, well at least not on mine, more like 12oz, which I have no prob with, however I have noticed on mine that its starting to wear in places, its been re-waterproofed and doesn't leak, but something to consider when looking.
From a tent point of view mine only has a semi canvas type floor, I don't know the exact name of the stuff, but it would be better I think if it was a PVC type floor, they may do this now, but as mine is a 2008 model it doesn't have it.
