Just received confirmation my dolly shipped today..... Ordered a few weeks ago and description suggested it was compatible with my 260B. Before my order shipped they received info that the current dolly may not work as they had hoped with 260B so they delayed my order until they were able to test with a 260B. After testing it appears some changes were needed for use on 260B. Situation was handled professionally. Ryan was very helpful through the process. I am looking forward to putting the dolly to use. Will post pics when it shows up.
