You say your clothes are optimized… but Nemo jazz is a 30deg bag and I’d be shocked if you tried a zero deg quilt with the right layers and couldn’t make it work.
I find my 0deg quilt plus alpha fleece and wearing my (dry) rain gear is good well below freezing even cowboy camping with a breeze.
But you gotta practice and iterate.
TLDR: the bags/quilts you tried might not be your problem.
Since it’s temp controlled, I think any sleeping bag will work. I think it just depends on your budget. I have a Nemo jazz that I use for regular camping. When we sleep in the car- we just use a sheet and a blanket. Good luck op.
This. I hate mummy bags. I move too much in my sleep. My Nemo takes up a bit more space in my pack but it is so comfortable and a good night’s sleep, where I can fully roll around in my bag, is worth it. I will never go back to a mummy bag.
