The "round thing" is a collapsible bucket used as a sink under the blue water container. As GBL pointed out, porta potti is on left side, rear corner. Got it from Walmart. Brand isn't so critical but had to make sure the height was under 12"....as I recall. The 12" bench height was chosen for comfortable head room while sitting. Didn't realize how that arbitrary height would effect further development of features.....like food & equipment , storage box sizes that would maximize the storage space under the sink cabinet. One more inch would have accommodated the optimum standard sizes of plastic containers.
Bought the Van little over a year ago. Love the concept & design but convinces me American made, at least for Ford, can't match current and past Toyota's I've owned. Ford has a rougher idle, visors that work there way to falling off, slightly loose driver door handle, detached door rubber seal, and lately intermittent front power window interruptions.....and a few times under hood 3 seconds of rattling noise in the drive belt area on start up, and twice on start up a strange slow "groaning" noise....like maybe ABS brake sound or dry rear wipers under stress? Van has less than 70K miles, had good car fax report and showing regular maintenance and appears really clean.
Next addition? Front slider curtain between front seats and end of beds plus side & rear window curtains..... and maybe roof vent.
Have already made a major change from the pictures. The preset table wasn't as necessary as we thought it might be. discarded the removable legs & lay the table top across the ends of the bench in the back. Serves as a good enough table to ones side when sitting on the front ends of the benches and makes transition to the front bed location even quicker. Still utilize a 2nd layer bench panel to move forward for the other bunk.
Thanks for your responses & comments
