Just put the Hest Dually in standard camper. Fits perfect. There’s clips on either side of the mattress that need to get tucked into a pocket on the side or else it could wedged when the camper is closing. Has a phone pocket on the end with and a zipper that easily pops the cover off to wash. First impression this thing is super comfortable. I like the idea that it’s basically two different mattresses with a seam down the middle, and can fold the mattress in half when I camp solo to get even for comfort. Next trip is beginning of June where I can give a better impression of this thing.
