Thanks for asking....it was definitely a good move. I am a fairly good size male and the 300 had some limits with my weight and staying up with bigger units of same or different make. I would do it all over again. One thing noticeable of course is the weight, I didn't struggle at times with backing or moving the 300 about but with the 500, the weight difference is very noticeable in doing the same. I have a bad knee but even still I am able to do want I need to with a bit more effort. Also, even though I had many good comments on the 300, I get many people coming over and asking about my white 500 RI and the words from them was all very good at what they were looking at. The gas, well, as can be expected, the 3.38 gallon tank doesn't give the mileage the 300 did of course but rest assured when you want some power and speed, it is there and than some. You will not go wrong with thinking up for sure. Good Luck!
