Google some Ranger forums and you will find some Ranger owners that use it as a toad with no problems at all. That 55 mph limit may have applied to older Rangers but not with the new ones.
I bought a 2019 Ranger and installed the Roadmaster base plate. It was an easy install and looks good. I haven't pulled it behind the MH yet but don't see any problem arising. The Ranger even tells you when you have it set up for being towed.
From the manual:
1. Put the ignition in the on position, but do not start the engine. If your vehicle has an ignition key, turn the key to the on position. If your vehicle has intelligent access, press the engine START/STOP button once without
pressing the brake pedal.
2. Press and hold the brake pedal.
3. Rotate the four-wheel drive switch to 2H.
4. Shift the transmission to neutral (N).
5. Enable Neutral Tow by selecting Settings in the information display menu.
6. Then select Vehicle.
7. Then select Neutral Tow and follow the instructions on screen.
Note: If successfully completed, the information display shows NEUTRAL TOW
LEAVE IN N or Neutral Tow Enabled Leave Transmission in Neutral. This
indicates that your vehicle is safe to tow with all wheels on the ground.
