I know the engines and undercarriage are identical, lifting capacity nearly identical. As far as anyone knows is there any advantage to having the chassis specifically built for the track machine? I could go either way, but am leaning toward asv. The dealer is smaller, a little more personal in service (the salesman is also a partner), but I know Cat has a larger parts inventory available and a bigger dealer network. Contrary to what I have read, the Asv is actually priced a little higher, but he came down to match the Cat price. Any advice would be appreciated.
