On the early tractors they used a cylinder connected to the exaust to raise and lower planters and bedders thought this might be of use but I bet it can be done.
So you need to put all your time and effort and moneyinto building your car/truck before you know if you can even get a Title. Thats sounds so wrong! Thats not good advise (not saying you are wrong) but I would have to see if I could get a title before I started.
