So, I just bought my bus, and now we're struggling with the plan we laid out several months ago of raising the roof with a welded vehicle. I just noticed the aop mentioned avoiding cutting into trusses. is this really a problem structurally? the hole we were hoping to cut would be about 4 ft length or so, up at the front of the bus just behind the drivers seat... not sure how wide (still considering what vehicle will go up there, or if we should makeshift the whole structure out of sheet metal and extra windows). just under would be the living room, roof would only be raised 3 ft, like an overcab bed space. total length of structure about 10-12 ft.
also, how significantly does the weight affect maneuverability or gas mileage?
