It’s probably a winch for an extension mechanism.
It is directly driven by the van door motor
Whats the motor behind the spool? It looks like it has the same end as the van door.
Alex, That spool sure does look familiar. Is anyone from 115 working with you guys this year?
I was going to say the same thing… looks exactly like the spool on your 2003 bot
Yep, we got Ves helping us this year.
