I equate the differences between the two cranes for the difference in model years. Kind of like a Tesla Model S from 2016 and a 2018 one. Thank you Mcminsen for the side by side picture comparison. This one also took longer to install I think. Glad to see this project continue to move forward. The neighborhood could soon have quite a few cranes which will be nice.
