Salivanto,
I'm in a similar situation except that I'm only 6'4" and only have 2 children. I'll be interested to see what direction you're going. Right now I'm thinking about doing a teardrop with an exterior like Rob's Cabin Car, except that the doors will be located in the section completely towards the front of the trailer for upper bunk clearance. Inside there would be a top/child's bunk that goes all the way back to the outside of the hatch for upper bunk leg room and lower bunk head/sit-up room. The adults would be on the floor and the kids above in parellel with each other, this way I can reach up and dope slap them if they're not going to sleep. I've been thinking about making these bunks out of hollow-core closet doors and keeping them sectional so I can remove them when their not needed or fold them up for shelves and to section off the galley area later. I'd either have a short hatch on the back or perhaps a short hatch that opens out from the top down to become a work surface. The traditional hatch makes me nervous because even at 6'4" If I had a nickel for every time I've hit my head on something...well I'd only have about $3.50, but still... Access to the bottom storage can be had from the side and still look nice in a cabin car style. I don't think a 4' height is going to work though, so I'm considering a 5' tall one, but that's easy to accomplish with the cabin car look too. Anyhow, I'm still at the dreaming state so I'll be watching to see what other folks do. I've also been looking seriously at that pop-up vardo design. http://www.tnttt.com/viewtopic.php?t=3740
