In general . Look under the chassis. Look for red and blue pex lines with screwcaps or petcocks. Open them as well as sink faucets to vent the lines for draining.
If you see that the red line is capped and the blue is open ended, then that blue line is a 'dual purpose line' which drains your freshwater tank as well as the low-point line. There would be an "interior mounted valve' near the floor to gravity drain the FW tank.
Draining low point drain lines takes very little time because its a small amount of water.
If you have the dual line setup then the blue could take longer depending on the amount of water in your FW tank.
Three most common areas for low-point drains is near the water pump, freshwater holding tank or exterior water gravity fill port .
