i'm going to be in a position soon where i can invest in a van for my business, which is going to require a lot of travel. i've done some research regarding veg oil, attended a lecture and spent lots of time on websites, but soon i have to think about actually putting what i've learned to the test. a veg vehicle makes sense to me economically, as well as enironmentally, for the time being. i'm willing to invest to get it done right, but i also acknowledge i'm learning. i have a limited amount i can invest, so i have to spend wisely. what are the first practical steps to take to go from just reading about veg cars & being excited about it, to actually converting and driving one?
