I can find nothing in my manual where it says, “that at 300 pounds of tongue weight you need a Weight distribution hitch”. My manual says that, “A load equalizing hitch is recommended for loaded trailer weights above 1,000 lbs (454kg).” - A very low standard in my opinion in either case for this vehicle.

I have a friend who is a lawyer who tows a medium sized popup without an equalizing hitch or electric brakes. He says that manuals are written by lawyers not automotive engineers. This is a bone of contention with me because if you have an accident a lawyer will trot the manual into court and ask you why you did not follow it. However, the key word in my manual is “recommended” not “required” leaving some judgment to the individual. My assertion would be that if the newer bigger popups come with electric brakes those brakes should be hooked up and working.
Also, I tend to forget sometimes that towing a 5,000# boat and trailer is dramatically different than towing a travel trailer. With the boat and trailer combination the bulk of the mass of the unit is located over the twin axels that are at the rear of the trailer where the engine, out drive and widest part of the boat rides. Very little of the mass is located near the hitch, so the Liberty just has its way with it.
