Hi oily, Jings, some of those pepper pot tanks for animal feed can take up to 11 drops, just imagine going round some of those Dumfrieshire or ■■■■■■■■ farms with an outfit like these. I remember it being bad enough with a two compartment tank or a 3 compartment box bulker both on a rigid 6 or 8 wheel chassis.
