The plunger-style holder on an RV entry door takes a lot of abuse from wind and repeated use, and eventually the socket wears out or the metal plunger stops catching. This RV Designer replacement holds the door open the way it did when the rig was new.
Swap it out when the old holder stops gripping or the rubber socket has cracked, and stop chasing a door that won't stay put.
