Thanks everyone for the advise and interest in the auto train, The update is they say you need a minimum of four inches, No problem the XF has 4.9 and they told me there will be no problems in loading and securing. We are heading to Daytona in a couple of weeks and will make a stop at Sanford to pick up our tickets for the trip. The wife is happy that she doesn't have to listen to me complaining about the way people drive lol. Thanks again for all the help and humor....
