If you haven't already got a Pre-Delivery Inspection Checklist, there is one available to our forum members. You can view it by going to the Keystone Questions section of the forum and look for the sticky "Pre-Delivery Inspection checklist " at the top of the page. You can download, print and take a copy of it with you when you do your walk through at the dealership.
Many members have taken advantage of this and have reported back that they found it very useful and were glad that they had something to check off.
I hope all goes well during your walk-through.
Welcome to the forum and we're looking forward to hearing from you when you get your new toy.
