The outside of the new Rhino has a timber frame support structure. This timber frame adds panache to the exterior and creates the base for insulation on the outside as well as for a trellis above the cargo doors. The bunk bed behind the cargo doors and the trellis were crowd pleasers on the Zulu Queen. All of that stayed. I made minor adjustments to the timber cuts. The timbers are made on a very expensive CNC machine which happens to reside about 3 miles from our shop. The modifications make the timbers fit like a glove. The actual roof got a minor overhaul though. Instead of a rubber membrane roof we changed to a corrugated metal roof. The design team felt that the corrugated metal was more aligned with the nature of the container. It is also a roof design that can be accomplished with carpenters rather than specialized roofing contractors. That was a nice simplification in the construction process. Before the roof goes on, we will fill the 7″ cavity with closed cell foam. I think I have mentioned before in previous blogs that the creation of the roof does two things. It allows us to insulate on the outside. This is good because it preserves ceiling height on the interior. And it creates a waterproof surface above a waterproof surface. Yea! That is so cool and is major reason that I consider this an heirloom product, ie. one that can be passed down from generation to generation.
