Horse lorry ownership costs?

anyone run a 7.5T lorry? im trying to find out about the costs to own one such as MOT (plating) tax, tyres, etc? again just so i can get an idea.

SMBo currently runs her fronty as a second car just to tow the nags but would like to get a lorry.

Hi there, per year:
Insurance: £259 to £320 fully comp approx depending on excess and mileage & NCD
Breakdown cover: £119 approx depending on cover
Tax: £125 to £185 depending on the year of manf
MOT/service: up to £250 - £1000 depending on who does service & taking to test centre

also see the paper work before you buy as it is classed as a 7.5t gvw
but if the unladen weight is 6.5t you wont get a very big horse with all the tack in before you get to weight limit
also ask to see the garage reports in case its just passed its plate and its on its last legs
