I did mine opposite way adding hgv when i had psv…
I had to do everything to get the licence…but already driving large vehicle you should be ok to cut the amount if training needed short.
As said there is no money in coach, i use to work all the hours and still take home naff all…tips are non exsitant now so can not rely on them to top wages up.
Deffo do less hours now and earn more and see family more, have a life again.
