Although I did not buy a gasser, what you actually observed is what I finally summized and I am glad my research mirrors your real experience. If it wasn't for the elevations I frequently climb out west, I would not have spent the extra on a diesel.
Gearing is a huge factor on well the engine performs at your given load and speed. I chose mine based on my driving speed while maximizing capacity. Going to lower ratios would leave me using less of the transmission range and going higher would limit my top cruising speed.
