All sounds good, Rob :ebiggrin:.
I'm certain that I will work out all sorts of these things within the first 24 hours of camping in mine, as others have said already ... :iconwink:. Hopefully I can learn some more tricks from you since you have an extremely similar setup to my own.
It has crossed my mind (short trip, these days ... ) as to how effective the silvered canvas will be at keeping the heat down. I will keep your specific solution as a bookmark for future reference. I am going to visit Steve Holland at OzTrail in Brisbane when I (finally) get there. He's one of the engineers/designers there.
My model has huge windows all round. Three in each of the two main parts and lots more in the sun room annex walls, I believe. I haven't even unpacked the latter!
I have made a travelling cover cover out of a SCA PE tarp. As mine is always parked in the sun and weather, and the OM states that while the travelling cover and tent are made from UV and weather resistant materials, they are not meant to be exposed to these 24/7. I priced replacement travelling covers at between $400-1,000!
It will also protect the travelling cover proper from on-road damage to a large degree. At $14 from SCA, it is just a tad less than the abovementioned figures!
If you wanted to fit Subie rims and hubs, you could possibly fit a drop axle and rearrange the springs and hangers. Just a thought. This also depends on how much clearance you have to your existing guards.
BTW, if you want to start a new thread in "Campers and Vans" here:

I will move all our CT related chatter over there, rather than it cluttering up your car journal thread
:iconwink:.
