I tour with my wife and we have pretty similiar gear which has worked perfectly for dozens and dozens of nights.

Down sleeping bags having a comfort sleeping temps below freezing. They actually work even during heatwaves as blankets when temps drop during the night. And of course it's nice to have a bag that can handle the occasional surprise freeze.

cocoon bag liner. Easier to wash than the bag or pad.

Inflatable full length sleeping pad. I have a thermarest, she has an exped. Very comfortable when inflated correctly. You get a feel for that stuff.

Inflatable pillow and a cotton pillowcase. Probably the most important item on the list.

MASSIVE three person tunnel tent. This one is actually pretty new but it transformed my ability to sleep on tour. In our old small two person tent I was always a light sleeper but in the new one I sleep the same as I do at home ie. very well. Having space to sleep and live in ias a total game changer for me. Having the huge abs for gear, cooking, hanging out is a bonus too. The kicker? Weighs less than our old smaller tent and has way better ventilation.

Oh and the tent has an extra footprint because that's just nice
