Ok...originally my 8x5 boxy was rated for 750 kgs... I blew that out pretty easy....I then changed springs to 1,150 kgs (7 leaf)....and was blowing that out too ....putting some big scoops of topsoil on !!
Sooo...I just installed new springs again rated at 1,400 kgs...(9 leaf) farkers are huge !!!
I reckon I'm at my limit for the single axle set up...LMAO
