Coleman ComfortSmart Deluxe cot
Version 1 of my Element CaRV was to just fold the passenger side seats flat, jam throw pillows in the uneven spots, and put a thick inflatable camping pad on top. Some nights, this worked great, others, not so much. After lots of research here and looking at other solutions in many other vehicles via YouTube, I decided to give the cot approach a try.
At 6'2", I opted for the Coleman ComfortSmart Deluxe, at 30"x80" it's slightly longer and wider than the standard model, 25"x69". It just arrived the other day, and man is it a close fit on the width! The standard ComfortSmart cot would probably fit here perfectly.
Note that this cot also comes with a mattress which is not in the photos.
Due to the wheel hub, the cot is at a slight angle. I think the narrower standard model would fit here more ideally. I am tempted to order that one as well, and see which one works best. But it's nice to have a full-length bed. As @Michiganman said, comfort is a requirement here. I've found as he has that it makes a massive difference as far as how much I'd sleep in the Element when it comes to how comfortable the sleep was.
Next step is to create some sturdy elevation props for the bar legs, to get the middle and rear legs to a height level with the front legs, which are sitting on the passenger seat.
Anyways, photos below. This is step 1. My much-handier-than-me cousin is going to help me build the leg props and maybe some storage on the left side.
I need to haul specific stuff with me, as I'll be working on the road as part of many of these trips. The folding table and plastic bins will fit perfectly under the propped cot. The canopy will fit to the left, but eats up all that vertical space sitting on the floor. Need something over top of it.
Going to invest in a heavy duty cooler, so need room for that. As well as food and cooking gear. But those shouldn't be much of an issue.
I'm just glad the cot worked out to my rough interior measurements. Now the fun begins.
