@Bob ~ Thanks again. I tried to heed the advice I got here about insulation, to keep the build on the cheap, to keep some parts flexible so changes could be made later, etc.
@Jannecco ~ Bed build follows; hope it will help when you start measuring your available space. If you're going to use 2 x 2, each is really only 1 1/2 x 1 1/2. Other than that, just start adding up everything you want to do until you're sure everything is accounted for and everything will fit in or under and that extra 1/4" here and there helps a lot for ease of sliding things. I had to drag my knowledge of fractions out of the back recesses of my mind and was very glad for my pencil eraser. Yes, the aisle is a prime reason for using this design and it has paid off! It is just wonderful to be able to get up normally in the night and go to the back of the van where the bathroom is. I don't know that I could crawl over my hubby any more without doing him bodily harm ha ha!
WHERE TO SLEEP?
I posted some bed photos in response to Gaunt Dusk's request on his "The Great Debate...on beds!" post, but here they are again to keep everything together in my build thread.
Here's both beds out:
And the small bed under the couch/bed:
In thinking through layouts, my first idea was to build one bed across the back that would condense to a day couch and extend frontward to make a big bed. That was ok and would have provided some kind of 'square' space in the middle during the day, but I wanted to imagine other possibilities. I ended up on Excel doing up some layout plans... I know there are programs to do that but I did ok with Excel... I made two narrow beds across the back and tried to squeeze an aisle between them there. It was only about 7" inches wide and I couldn't see that working too well. Both those designs would have made entry/exit at the back doors impossible or very difficult. One big bed across the center of the van could have worked. I've seen photos of one that works well for the couple who built it. Their bed turns into two opposing 'couches' during the day, but at night it cuts the van in two, and one person still has to crawl over the other to get to the bathroom. I toyed with building a front bench seat to replace the driver/passenger captain's chairs, one that would fold out flat and become a bed. That was complicated and impractical.
Then it occurred to me to do a couch/bed with a trundle bed under that, when in the couch position and combined with the swivel passenger seat, would make a great living space! I realized that with the trundle bed out, it would still provide entry/exit at both the front and back, it would be easy enough to hop in the driver's seat and take off if need be. Also, as I mentioned, it would allow us both to easily rise during the night to heed the call of nature.
The van walls in the middle area are quite straight, so I did not have to do any fancy fitting. After accounting for everything that needed to stack under, plus the mattress thickness, I knew the couch/bed's height might be a comfort problem during the day. It would be higher than a normal couch. But hubby is tall and he said it would not bother him, and I could use a footstool if I felt the need. The inward curve of the upper wall also would be a problem. How would I make a day couch backrest that would have a comfortable slant when the wall curves the wrong direction?
How long would each bed need to be? The couch/bed would begin at the back of the driver's seat when it was in it's furthermost back position with the backrest extended backward, as this is where that seat must be if hubby's driving. That bed would need to be at least 77" to give him 5" extra for toe wiggle room. (I ended up making it longer so I could put the cooler on the end.) Mine would need to be about 69".
How wide? For each of us to be able to turn on our sides and do a little curl up, his could be no narrower than 32" and mine 27". The available width was 69" so I would end up with about a 10" aisle. Should work ok.
Mine, when pulled out, had to be high enough to slide over the top of the AGM battery box that would be built at the floor next to the kitchen counter. The bed's length determined the length of the kitchen counter, as I wanted the kitchen unit to have a ledger on it to support the end of the bed.
My bed would have to slide straight out from under the big bed about 10" and then toward the front of the van for a few inches, and then out the rest of the way and on over to the side door - this to clear the kitchen unit. That meant only two of the three front legs on the big bed -- the middle and front ones, would have to be positioned after the small bed was in the out position. The position of the middle legs on both beds would take into account the widths of the under bed bins.
Both driver and passenger seat backs would be fully upright at night and would make good backrests for bedtime reading and computing.
The couch/bed mattress would stay there. The small bed mattress would come off the small bed during the day and become the couch backrest. That would mean slicing it to about an 18" length and a 9" length and sewing both into a case that would bend so the smaller section would rest behind the larger section when acting as the couch backrest, yet stay together at night to be suitable as a mattress. Hmmmm. I'm not great with a sewing machine, so, like Scarlett O'Hara, I decided I'd think about that later.
The couch/bed construction was straightforward. I bought several 2" x 2" x 8' lengths for framing and legs, and I had on hand, from the previous owner's build, 3/4" ply for the platform. I made one back leg shorter to accommodate the wheel well and left two front legs portable. (I have a bin with various bits of wood for leveling things, so I just keep these legs in there.) I inset the front legs so as not to trip up on them. That meant putting the middle cross support in a certain spot so that leg, when positioned under it, would allow room for bins to slide by on either side. Every leg and cross support was corner braced and everything was glued and screwed. The back legs were lag screwed into the van frame after locating and pre-drilling the holes.
I added some plywood gussets to strengthen the legs of the smaller bed, since it would be moved a lot. I inset the back legs to account for the side entry well, and left legs off the end altogether since it rests on the kitchen unit ledger. Again, the center cross brace had to be in a certain spot so that its legs would not interfere with the bins when slid and locked under the couch/bed. I had some 5/16" plywood around and, after testing its strength between the cross sections, decided it would do for me.
Since using this system several times, the things I knew would be a little problematic have come true. When the small bed is under the couch/bed, the front weight of the couch/bed rests on it. That makes it hard to slide the small bed out. I am thinking about screwing a rope chain from the couch/bed front corner up to the cabover frame to take that weight off. I might screw guides on the floor for the bins so I don't have to maneuver them around so much. As for the couch/bed backrest, I have not tackled cutting up the small bed's mattress yet. Later LOL.
I also have banged the back corner of the small bed into the kitchen unit enough to scrape the shelf liner. No big deal; black duct tape makes an easy repair.
Overall, this sleeping/lounging system works great so far. I still have to drill vent holes in both platforms so the mattresses won't collect moisture.
