Had a few questions about our home built bunk beds...
Disclaimer: "Danger Will Robinson" absolutely no engineering went into this design, i.e. "y'all are on your own on this one..."
Kinedyne makes vertical e-track: We had ours shipped loose with the trailer, our trailer builder shipped horizontal e-track, said they had never heard of vertical. They fixed this later.
http://www.easternmarine.com/E-Track-Strips-Straps-Parts/I installed the vertical e-track on top of the floor/wall trim and attached it to the wall studs and wall panels.
For the roof, I cut a ~6 foot section and installed it into the roof spanning 4 sections of roof bracing to spread out the load. Note: I have found no evidence that e-track can be used overhead, it just worked for my needs. I nor the manufacturer have any idea how much weight the roof braces will support. I can verify that I made a sling out of the kayak strap and used a single anchor to test the overhead e-track and performed all kinds of circus trapeze acts to the amusement of the kids and the result was a rock solid mount. I had to use fasteners to mount the e-track if you can weld, so much the better. I reasoned that if I spread the load over the 4 braces using a single piece of e-track it would be better. Did the same for the other side of course. When installed the cot has 4 different support points, seems to be more than enough margin for our needs. The e-track, fittings, and straps are way stronger than needed. My concern is related to the mounting points in the trailer itself. Keeping an eye on that one, but so far so good.
Here's the wood beam end socket for the wall mount: I cut a short 2x4 and cutout a round slot for the cot pipe to lay in and made a clip to anchor the pipe into the wood.
Here's a picture during construction, shows the e-track beam sockets, and the overhead mount.

Here's the "flat" d-ring e-track anchor I used for the ceiling mounts:

Here's the cots:

http://www.easternmarine.com/e-or-a-tra ... hook-80023I'm sure there are much better ways to do this, I was just determined to stay on budget and keep the modular concept of the trailer alive. Can't believe how useful and versatile the e-track has been. I was going to remove the bunks when not needed, but now can simply un-clip the overhead mount, move it to the top of the wall, take up the slack in the straps and presto...the cots rotate up against the wall, and make lots of room for other stuff. The e-track looks pretty utilitarian, but we wanted function first.
Now back to your regularly scheduled program, thanks for looking.
