Always have a map, just in case the sat nav decides it has a sense of humour day 
I reckon the patey hat bag has more alcohol in it!
loads of ideas already but one thing I have which has proved to be a godsend on a few occasions is a full shoe removal kit. I also have a spare set of shoes for the horse, but thats mostly for horse trials etc where a farrier is onsite.
my dogs have their own stuff in the lorry too, including dog tags with the lorry reg and my mobile on them
for a three day, I'd also take an extra door mat to have at the bottom of the lorry steps, then you can wipe feet before entering the lorry. saves on mud.
Spare cash hidden up. I regularly forget my purse and 10miles in realise I need diesel!
Emergency phone numbers for break down, vet etc handy to have copies in lorry.
Jack thing for changing wheels!
