all a relay does is turn things on and off. if it is a dual 87 relay, it has two outputs that it turns on or off. though you can splice as many as it will service adequately.
the relay just has contacts in it that are put together or held apart by an electrical solenoid. the solenoid is triggered by whatever is the providing the on/off signal. the reason for the relay is current handling. it can handle ALOT more current than a regular switch can in most cases. the relay can be normally open or normally closes. (NO or NC). that just means if it is normally open, that means you have to activate the relay to have your lights come on. if it is normally closed, your lights are on until you activate the relay to turn them off.
the relays are 5-6 bucks or so and will not be the metal can ones like you likely have on your coach now.
the flasher is just a switch that turns on and off at a certain interval. the regular cheap flashers are thermal and make that ticking sound as it cuts in and out. normally all things that are attached to the output side of the flasher should either go on or off together. the one thing that might happen is if something on the output side requires a certain amount of current to operate and something else on that same side requires less current to operate, then you might have two outputs of the flasher operating differently. that would likely be mostly with something "electronic" like led lights. a regular filament bulb just gets dimmer with less power.
didnt really answer your question, but some info to chew on
