I am an electric truck fan and feel that in the end they will be the most popular and correct choice for most jobs. Batteries are not very environmentally friendly and any improvement on lead acid is very expensive. The fact is that most customers at the moment are looking to change to LPG from either diesel or electric because of the figures available at the moment and the forecasts for costs for the next 5 years. This is a can of worms and ultimately the winner will be the power source any customer chooses based on the information available (and any government pressure applied to favor one ahead of another).
