What is your opinion on the 3' add on unload auger extensions? I run a 2377 with a 30' platform which makes unloading on the go tricky. Would like 3 more feet. I like the Shoup model that adds a section of auger rather than the Abilene one that just adds a section of flighting to the end and pushes the grain the last 3 ft. Experiences? Thanks.
