Stuart,
one of the most compelling man maths arguments I've ever seen
So by reducing the depreciation on Tarka the E3W is essentially free.....!!
Just take this one step further - as you have a generator the EV3 will be free to run so saving you the cost you would have incured with Tarka.
So an EV3 saves you money
And what do you do with the money you've saved? Why take Tarka out for a spin of course
