I bought the single version of
this. I like the pad, I can control the air that I put in it to manage how much cushion I want. It's thick enough and it's not like an "air mattress" that two people really can't sleep on.
The downside is, if you want to roll it up, it takes up quite a bit of room.

I bought the full size (50"x77") version of that when I couldn't find the ExPed Mega Duo for sale anywhere.
It inflates pretty quick through four valves and doesn't really require a top-off from a pump. It's constructed OK, but I think the ExPed version would have been worth the premium for the better materials and maybe a slightly smaller packed size.
I've only got one night on it so far, but it's very comfortable. I use it in conjunction with a Big Agnes Dream Island bag and it's a really nice, if bulky, setup. The one night we used it, it got down to the mid 20's and we were plenty warm. The real test will be whether or not it's too warm for the summer.
The packed size is big. 50" long and 12-14" in diameter. It fills in the back floor boards of the 4Runner with just enough room left over for a small bag with our camp pillows and throw blanket. Not an issue when it's just us and the dogs, but if we had passengers in the back we'd have to find a new place for it; probably on the roof in a waterproof bag.
I will say that I'm going to buy another bag for it since it's a real pain to get back into the bag that came with it. I found a huge, cheap duffle on Amazon and I think it'll be a lot easier to use.
