I'm 6'4" 360 lbs. I use this Teton sleeping pad [https://www.amazon.com/dp/B000P6DJ8O?th=1](https://www.amazon.com/dp/B000P6DJ8O?th=1) and/or a Therm-a-rest pad [https://www.amazon.com/dp/B00HANOZRY?th=1](https://www.amazon.com/dp/B00HANOZRY?th=1) The Teton pad is not small, but if you are just setting up camp near your car they are great. The Term-a-rest rolls up small enough with my wool blanket to strap on to my backpack and is easy to carry around. It just isn't as comfortable alone.

I don't know what the bed of your truck calls for but this plus a few thick blankets makes a very comfortable pallet pretty much anywhere, ime.
I would suggest editing your post to the RidgeRest Classic although I knew what you meant. I’m a big fan of that CCF pad and use it quite often.
[Exped FlexMat](https://www.exped.com/en/products/sleeping-mats/flexmat) and [FlexMat Plus](https://www.expedusa.com/products/flexmat-plus?variant=42267057029337)\* were available in LW size (77"x25"), now replaced by [Flex 1.5R](https://www.expedusa.com/products/flex-1-5r) and [Flex 3R](https://www.expedusa.com/products/flex-3r)\*, still in the same sizes. [Thermarest RidgeRest](https://cascadedesigns.com/products/ridgerest-classic-sleeping-pad?variant=41316889657478) Large is also 77x25" inches. [Seek Outside Matty McMatFace](https://seekoutside.com/matty-mcmat-face/) is 80x40". [Gossamer Gear Thinlight Rolled Wide](https://www.gossamergear.com/products/thinlight-foam-pad?variant=42879197511734) is 58x25". Mountain Laurel Design Goodnight is available in 80"x40" in both [1/8"](https://mountainlaureldesigns.com/product/goodnight-eva-1-8-foam-pad/) and [1/4"](https://mountainlaureldesigns.com/product/1-4-foam-pad/) EVA. (\*) The FlexMat Plus has large dimples that some people dislike when new. They flatten some with use, or can be covered by a thin EVA pad (Thinlight/GoodNight/Matty McMatFace).
Um, take another look at my post. The second item is the Thermarest RidgeRest. It's popular for a reason (just maybe not *ultralight* reasons). Thermarest also makes 23" wide pads in both CCF and self-inflating, like the ProLite series, for the military.
Speaking of this, [Alex Hibbert demonstrates using 5 layers of CCF for -40 weather](https://www.youtube.com/watch?v=mTP1ZcPXn8Q&t=282s). It's an older vid from the same guy that BigRob mentions, but it's more directly actionable since Alex has not finished designing his new system yet. It can be done, and there are some reasons to do it, but "lightest weight" isn't one of them. For weight and bulk, air pads win. As Alex points out, one of the features of inflatables is that they can "uninflate", which is an issue where he's going. But he's a bit north of the PCT... As MoonSandals suggests, you're going to have to do more testing for yourself. It's not super complicated: just add layers until you're comfortable. Some noteworthy pads to consider: * [Exped FlexMat Plus](https://www.expedusa.com/products/flexmat-plus) (thickest accordion-style pad due to large dimples). Some people like to use a flat topper over this pad. * [Nunatak EvaZote](https://nunatakusa.com/59-ccf-sleeping-pads-genuine-evazote) (high density version of smooth roll-up pads, available in several thicknesses). * [Thermarest RidgeRest](https://cascadedesigns.com/products/ridgerest-classic-sleeping-pad) (thicker than most other roll-ups).
Pulk\*. Alex skied half the length of Greenland (and back) in four months, unsupported. That's the ultimate in "ultralight backpacking", but not the way we usually think of on major trails with towns every few days. [Longest Unsupported Polar Arctic Journey in History: story of world-record 'Long Haul' expedition 4K - YouTube](https://www.youtube.com/watch?v=-dfrNqPwVgo) (\*) CCF is bulky but not especially heavy. If necessary, you could strap more than one to a backpack without shifting the balance.
Maybe. I recently got an Exped and a RidgeRest to try as a pair, similar to what you describe. They are comfortable enough on the floor, but I haven't tested on roots and rocks yet. The Exped pad is available in a wider width than most other accordion pads.
My dog's half-husky claws convinced me to switch to closed-cell foam. I frequently use two sheets - a smooth blue walmart foamie and a classic ridgerest. That cheap blue walmart foamie makes a great sled when you just don't want to downclimb from a winter summit attempt. I am more comfortable on inflatable pads, but I'll save it for base camp.
just a heads up - the Exped 3R is an inflatable pad, not CCF. if you specifically want closed cell foam, the RidgeRest Classic is the way to go from those two. if you're open to inflatables though, the Exped is way more comfortable for side sleeping since CCF pads are pretty thin and firm.
