John, thanks for all the details. What a creative, great looking bus you have created!
I have heard about the life of wrap being something like 7 years. I think that is quite conservative with today's great materials.
We had our service truck wrapped 2008. I had built a topper for the service bed and then had the whole truck wrapped. When we closed the business, I dismantled the topper and kept the rear door (good metal parts for some project

). That door has never been indoors and still looks great.
Darn, I miss that truck
Jim
