I've actually done that once already. When I first put down my deposit I had just signed up on a 3 year lease earlier that year. That lease is now up and I turned the truck in thinking I'd get my R1T this summer. Now I'm not so sure I'll get it this year. I haven't decided yet as I'm waiting on more feedback from others with their guides but absent good news I may start my search for another F150 as I need a truck at my property.Why not go through with the lease...by the time its up in 3 years your Riv might be ready?
