To prepare for the trip I recently swapped the rear end for one out of a '99 Police Interceptor. This had to be done for rear fender clearance. With the wider, lower offset wheels the tires have been rubbing when the rear was lowered which could be trouble if one of the bags had an issue on the trip. The earlier rear end is 7" narrower, allowing plenty of clearance. This keeps the truck drivable in the case of a rear bag failure. Since I was switching rears I found one with Trac-Lock and 3.55 gears (previously was 3.27) for better acceleration and traction. I was a little concerned about mileage after the swap, but I calculated the mileage at about 20mpg going over 70 most of the way with windows down (and even 80-85 through Idaho). We made the trip home in 12 hours with a couple stops for meals, a couple fill ups, and a rest stop.
I've posted a video on YouTube that has pictures and video highlights of the trip, you can view that here: https://youtu.be/jVHuX9QFwuw
Here are a few pictures of the truck on the trip:
