Hi. Thanks for the replies. We tried the solar water bag and its a no go.
Too cold here in Canada. An ice bag might work though.
The paint idea is actually pretty good, lots of really decent plastic paints now that really adhere so yea. Good idea.
The aluminum door and frame i can make with no problem as i fabricate in aluminum every day so that is not a problem. I dont want to make things more difficult than necessary though. The cut i make in the aluminum skin can be the skin of my new door so matching will be perfect. I want this door as small as possible so i would just replace the door and frame of the kit.
Next question. Whats a good kit with good qualty materials? I see some all plastic ones on the net but they look sort of cheap, the knobs look how you say.....cheap?
When i do you install i will take picures so others can do the same.
Much appreciated for the good ideas.
