Got some constant squeaking going on. Best guess is that its coming from where the cab sits in the cradles and is locked down. Anyone else have this problem and know the solution. Looking at the hooks in the center of the cradles, the left one clearly had a shining part on top where it is rubbing on something. Not certain if that is the source of the squeak. Cab sits on a couple of rubber bumpers on either side of each cradle. Not sure if they wear. Also not sure if the lock down hooks are adjustable and can be shortened to hold the cab tighter in the cradles to eliminate squeaks.
