So what happens if you are at a station y'all aren't usually at and it needs to be towed?
There's a ground handling checklist/QRH kept onboard those aircraft that is then given to the ground crew at an outstation to follow, regardless of whether they are familiar or not with that aircraft. Which makes sense. It may not be in the flightcrew checklist, but there is still a checklist for it, as there are things that have to be done with disconnecting nosewheel steering on some planes, tow turn limits; and if the ground crew is in the cockpit instead of a flight crew: things like brake riding and parking brake usage, whether/how emergency brakes are used if needed, and any related notes/warnings/cautions to the operation.
For some of these aircraft, towing is a complex enough operation that I can understand why it would require a checklist, as critical damage to some components can occur if certain items aren't set correctly, etc. It's indeed far more than just hooking up a tug and pushing/pulling the plane around.
