Turn Signal Flasher Unit(S)

I was told to change my turn signal flasher with a heavy duty one for towing. I went out to NAPA and bought one to install in my MH. But when I went under the dash to change the flasher unit there were 2 flasher units? Does anyone know why 2 flashers are used in a MH?

One for turn signals, the other for emergency flashers. You might have already had a heavy duty flasher in the RV, they usually are, especially if your trailer light harness was already wired to the outlet at the back.

One flasher is for the turn signals and one is for the 4-ways. I'm pretty sure your Workhorse already has a heavy duty turn signal flasher. Mine did.
