I think it's a brilliant bit of work
@Dobbie and will be using it myself, even though it may scare me.................it is a "How long is a piece of string?" subject as there will always be that little bit more info...........................rating allowances for tyres and suspension ??????? I think it's load to 90% of stated ratings, so that throws another bit into the ring........especially as some vans the tyre, rim and axle rating can be near the limit . My old Tardis had 900kg tyres fitted new so when loaded, 1800kg, it was maxed out................and only had 1ton rated rims....until I changed them all.
Need to have the spreadsheet as an easy to get at sticky on the main page........................Moderator guru's.................?????????
