Transfer ownership. Kiss your truck goodbye! That's a good new scam. A company has no business telling you what to do with your title. They may ask for a copy as proof of ownership. That is if you really are an "owner".
If I buy a truck it will not be financed thru the company I lease to. I will ask why they need the back signed. but more then likely I will not lease to this company. I don't know of another way to finance a truck tho without changing from company driver to owner/ op at this one. I also don't feel like doing the lease purchase thing again as that was too demanding.
