I agree. There are very simple technical reasons that make a very good ground system the most effective way to increase range. Standard antenna manuals and textbooks don’t cover this well because they are geared toward amateur and professional antennas which typically are much larger relative to the operating frequency and are not as dependent on a good ground. Part 15 3-meter antennas have pathetically low radiation resistance at BC frequencies. Attention to a very good ground system with very low ground loss resistance can multiply the radiated signal dramatically.
Height is a secondary factor, but can be important when a ground level antenna is surrounded by buildings as is the case when houses closely surround the antenna on all sides.
