I salute you Sir, you have done more than the rest. On the paint job, great, but may I suggest use some grey paint and ad some tree trunks, doesn’t have to be greatly defined, just a few semi vertical tree size lines. To go further, make a hard copy picture of you shelter from the most accessible view angle, (what people would see from road) and add the trees that are behind the container, not so much the real aspect of the trees, just a matching to the top. Keep it fuzzy, something that will fool a first glance with the same shade of color. Walk the route that people might see your shelter and this will determine the extent of camo needed, and be sure to break the outline of your box, nature has no straight lines. I hope this helps you, just advise from an ex grunt. Good Job and good luck.

Nice seacan! I am about to partake on the same escursion. Excuse my question but how much clearance would a truck need to unload a seacan?
If your talking height clearance look at 1/3 the length, that would be 3-4 ft for the trailer and then the off load tilt.

I anchored mine to a tree and rolled it off into place within 1" of where i wanted it. Total height of 11'7".
