Only used twice on a bike trip, but my camping setup worked well enough for me:

Two person tent for myself. I'll take the space/weight penalty for space for my gear. The odd times the wife agrees to camp, I'll give up the extra space to her, but if she were doing it regularly, I'd buy at least a three person. I've got both a fifteen year old Kelty and a Big Agnes that replaced it, mostly for a much better rainfly design that doesn't catch wind as much.

Blue foam sleeping pad. I've had two inflatable pads go out on me now, I simply don't trust them. Plus they're all of $6 at Walmart.

Sleeping bag is a decade old 30F synthetic fill bag from Gander Mountain. Its due for an upgrade, probably with down. Temp range works well in any camping I realistically do. Summers in MI can get down to the low 50s or even 40s at night, if its warmer I just unzip it.
