All this extra weight to carry around, second battery, heavy cables, the inverter, tea sugar cups etc and milk..........OH You will also need a fridge for the milk....:doh
So you won't be making tea all the time, so this extra weight will be carried for 99.99% of the time for no reason, thus increasing your fuel consumption.:doh
Boy oh boy, the cost of that one cup of tea is getting to be astronomical....
Cost-a lot-Coffee would now be a cheaper option.... £2.50 a cup :lol:lol
Have you though about becoming the next Chancellor? :doh
