I am looking at building a similar box and have a question or two if I may? I am from Saskatoon and have enjoyed watching your build so far and am excited to see it's progress.
XRACER144, being locate in Winnipeg I assume some winter "camping" in the truck is in order.
1) Are you planning to have the water and sewer system fully enclosed inside the heated box portion of the camper or use tank heaters of some kind?
2) How are you going to handle the black water tank for cold weather? Cassette toilet?
BTW, MCC, the maker of your bus fan seems to make some very nice products that may translate over to this type of vehicle as well.
3) Do you think the aluminum skin and frames of the ITB panels are strong enough to mount an awning?
