Exactly the situation. Travel in the cap, sleep somewhere else. I was pondering folding down the 60 side as well. And maybe the cooler can just be moved back and forth between the cap and the truck as required.
Why not just get the dogs a tent of their own?
For a cooler we have an Igloo Sportsman. It’s rotomolded similar to a Yeti and is certified bear resistant by the IBC so we can legally leave it outside in bear country, which is against regs in a standard cooler. Given we spend most of our outdoor time in grizzly bear country, the space it saves in the vehicle by leaving it outside while in camp was the driving factor for us getting one and has made a big difference in the amount of cabin space. It gets cable locked to a tree at night and when not in camp.
I have left my dog in a tent while I went out to use the bathroom and she did not appreciate it for even a minute and started clawing at the walls. I don’t think the tent would survive the night with my pups inside
What about an awning with the walls and floors off the side of your truck/canopy? They could stay inside that, safe and out of the elements, and still have a nice dry space to sleep in. That could/would also give you extra living room during the day.
I’ve got two huskies and would do one of two things...1. Get those Discobeds and stack em to create floorspace for the pups. 2. I’ve got impact case and container collapsible dog crates, and i’m guessing two may fit in the back of a mega cab. Bonus option is get some sort of go fast camper, vagabond outdoors, flippac, etc and sleep up high.
