My Bangbed arrived today and I quickly set it up in the cargo area. Much simpler than the Helebox. So much simpler. So so so so so much simpler.
It's a bit tight setting it up with the rear seats up, but my boys had the rear seats reclined back pretty far. I clicked them forward a bit and then the rear bed fit fine. It actually is kind of nice with this set up in there. It's not too high to still be able to load something heavy and bulky like a full cooler and it gives some nice storage underneath. I may cruise around with it installed as well and see how I like it.
As far as taking it down and stowing it for camping (if I need more vertical load space), the two leg boards fit nearly perfectly in the little dip area behind the 2nd row seats in the Overtrails. Then the 2 big boards just lay on top. The presence of the Bangbed wood would be even more unnoticeable if you remove the rubber cargo mat....or put the mat on top of the wood pieces.
The backs of the 2nd row seats still angle up just a bit but they do compress when you lay on them and it should be unnoticeable with a camp mattress & blankets on there. Our main bed is one of those adjustable things and we actually sleep with the head side up a couple inches so it's not an issue at all for me.
One thing that I do notice vs. the Helebox platform is the sleeping surface length. The Helebox platform was a full 70 inches because it went over the folded 2nd row seats. Now with this Bangbed platform and just the folded 2nd row seats, I've lost a bit of length. With my thick (4") camping mattress and pillow and a couple bags behind the front seats it won't be an issue. I'm 5'10" but if you're over 6 feet tall you might miss a bit of solid platform under you. The solution is to put camping gear (bags or whatever) behind the front seats to support the camp mattress under your head and adjust the front seat all the way forward. On another note, you also lose a lot of vertical room with the Helebox platform because the frame goes up & over the folded 2nd row seats.
Overall, I'm very happy with it. It is heavy as it's solid wood. I might use a big coring bit to drill out some material, but I also don't want to sacrifice rigidity. I think I'll dye/stain it black too, should look good with much darker but still showing the grain. The seal coat over the top. Or maybe just put black speaker box carpet on it. I'll keep you posted.
