Problem I have with wetting the CT Canvas is:
1: It's 15oz gague canvas
2: It's Dynaproofed
3: Totally 100% water proofed.
I bought the CT off a bloke who owns a Canvas Company. He ripped the original canvas off and rebuilt it to suit him. The canvas work and zips are worth more than the trailer itself. There is a tiny slit in the roof that looks like a hole but not once has it leaked even in a torrential downpour!
So I like the idea of putting a tarp over the top of the tent as a shade house effect. Might just work.
Any man, in the right situation, is capable of murder. But not any man is capable of being a good camper. So, murder and camping are not as similar as you might think.
