At the top right of the page is your name, "my profile" "settings", click settings and then on the left side you will see "my settings" find edit signature and you should be able to make it happen.
If you find anything wrong during the PDI, try to have it fixed before you take it off the lot... or at least get the dealer to sign off that it has been reported before you take it.
Yep,, spending a couple of nights in it will get you familiar with it.
Enjoy the Landmark and keep us informed... also you get the first year of Heartland Owners Club free, but you don't get a plaqe or anything,,, but you can attend a rally when you want. Think of joining us at a rally.. lots of fun and great people.
