I have a box of "tools" apart from the standard bits. All come in useful from time to time so I carry them.
Guaranteed the day you dont take it you need it
All fits in the trailer so its not too much really except when they want you to take the rubbish away - ok on a house but no so good if its a school - One job I removed 28 bags of crap
I am better now and have picked up my toys - thank you
