^^^^ wot Robroy said
A night trunk that long is a hard slog, certainly not something i’d be wanting as a new driver nor after years on the job, it should be a changeover trunk meeting the Glasgow driver half way.
Try it by all means, but set your stall out from day (or rather night) one, don’t be doing everything to prerpare for the run without your card in only slotting it in just before you charge out the gate with your arse alight, you really should show 15 mins of other work before departing to check your vehicle over clean the lights/windows etc, same on return not whip the card out as you charge through the gate.
Lets see now, min 15 mins from starting work, 4.5 hour drive each way, 1.5 hours of breaks, 30 mins changeover etc, 15 mins min when you get back assuming part of the job isn’t leaving the trick clean for the next victim.
So far you’re knocking on 12 hours and that’s IF the run can be done in 4.5 both ways and nothing goes wrong, @ 12 hours plus you’ll be hitting either tail end of evening peak period or joining the morning peak period when your eyes are out on stalks, then you have time travelling to/from work, when exactly do you propose to sleep or do anything other than work/sleep, hope its paying £200+ a night.
Tell you what that job is mate, its a killer, just entering winter going well north, freezing fog snow ice etc are inevitable, what might be feasable on a quiet moonlight summer night is a whole different kettle of fish when the weather changes, remember you’ll be in the dark the whole shift, you are right to only agree to 2 days but youy just know they’re going to try and force you (peter’s gone sick, charlie’s kid is in hospital etc) to do more.
