Car camping comfort champ, but some side sleepers find it thin.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I'll second this. I have this pad and have used it the past couple of hunting seasons. Plenty warm in below freezing temps, and cushy enough for side sleeping. I have the wide long version and it feels pretty spacious.
Hammock if I can, Big Agnes Rapide XL wide if I can't
What are you currently using? My sleep pad is the BA Rapide. It’s big. It’s heavy. It’s overkill at times. I don’t care. At 54 years old it keeps me going
They are pure luxury and I’ll never go back to anything lesser. I have a Thermarest air head down pillow that I use which is also considered heavy. Like you I am cozy and comfortable. Crawling into my fluffy sleeping bag and snuggling in with my pillow is absolutely dreamy and not a f is even about the weight I’m carrying. Soooooo worth it.
Shouldn't be a problem. For extrapolation I'm a big dude right at your combined weight, and I've been on the single size of that pad without issues for 2 nights. Bigger version, more room to spread the pressure, I think ya'll will be fine. If you plan on having activity time, I'd probably let some of the air out of the pad so it won't over pressurize and pop a seam if it's tested too vigorously.
I've got the Big Agnes Tiger Wall 2 Bikepack and recommend it, fits great on handlebars, in a cargo cage, or sideways in a pannier. I have the Big Agnes Rapide SL pad, and the thickness is nice after a long day in the saddle.
Spend the money. I'm kicking my own ass over the fact I was too miserly for too long. Never got a good night's sleep camping. Finally broke down and did a ton of research, watched several comparison YouTube vids. Settled on the Big Agnes Rapide SL insulated in the 25x78" size (I'm 6'3 240lb). I LOOOOVE this pad!!!!
