RayS,
Sounds nice and cozy, bet you can't wait for a pile of snow /w3tcompact/icons/smile.gif. I've been thinking about adding a marine circuit breaker to a switched relay for a "accy" block for lights, sprayer, etc.
I'd seen the Curtis hardside and the CozyCab units and your's looks great. Are you planning on removing it in the summer? I'm curious as to how the unit attaches/detaches as I'd prefer to remove in the summer rather than just pull the doors and open the windows.
Please send or post some more pictures!
Michael
