Starting own grab buisniess ? Help

30-40 quid to tip a load?
Where I work we currently pay 11 quid plus vat per ton to tip muck,and that’s cheap for the area!!
Fuel wise our euro 5 dad cf 410 averages just over 6 mpg-sometimes less
The euro 6 cf400 that I drive is slightly better -mid to high sixes…
Just had a brand new Entecon bucket fitted-four grand.
Burst a pipe inside the boom on Friday-(standard practice to replace all four pipes at the same time)just under 400 quid +vat (fitted them ourselves)
Buy my own grab?-no thanks,I’m quite happy to earn what I do for driving someone else’s and let them do all the worrying…
