Normal daily keyring: 4 vehicle keys (fuel keys are kept inside each vehicle), 1 fob, 2 house keys (house & garage), 1 padlock (gate).
As for camping, I have them split up depending on the season and therefore which toys are coming with me; they hang over the door inside the RV for easy access.
Normal RV keyring has ignition/door, camper door & deadbolt, compartment key (also accesses fuel door, water door, genset door), and hitch receiver lock.
Summer: Compartment key, cable lock (for jet skis), add'l padlock, JS trailer tongue.
Winter: Compartment key, cable lock (this time used for ATVs), add'l padlock, enclosed trailer keys (tongue, door, backdoor padlocks).
Of course, I have a spare ignition/door key hidden on the RV in case I lock myself out, and there is a full set of spares (normal/summer/winter) inside in case any of the individual keyrings are lost.
