The single most significant factor contributing to sleeping well while camping is to spend lots of time actually doing it. If the only time you camp is that one week a year you go hunting out West, then you likely aren't going to sleep well. Its not the same as your bed at home, its never going to be the same as your bed at home. But, regardless of what your setup is and what works well for you, when you lay down to go to sleep, it needs to be both familiar and comfortable. Familiarity and comfort is achieved through repetition and experimentation. If you spend 30,40,50 nights annually out in a sleeping bag, you'll be dialed in and when you slide into the bag, it is the 2nd most familiar sleeping situation for you: You know, by feel, the exact PSI your air mattress needs, what pillow combination you need and where you want them positioned, where you like your water bottle, headlamp etc and the sounds of the forrest are not foreign.
Show up to your $3,000 hunting vacation having not spent a single night in a sleeping bag that year, you're going to be complaining, uncomfortable, spending the first few nights dialing it in and getting comfortable in that environment.
