I used Monstaliner on both of my vans. I think its the best bang for the buck and the finish stands out. Its a lot of work to do it yourself, and you will get out what you put in. Skimp on prep, finish will show it. I just did my 01 and sprayed it in a paint booth. I could not be happier. No rock chips, pin stripes, nothings. Its essentially an epoxy paint that is tintable so you can do a variety of colors. If you have questions reach out, I have done 4 vehicles with Monstaliner and have learned a ton through the experience.

When I was shopping vans, I looked at one that had an older wrap. To put it nicely, it just looked like trash. I know they have a self life, but this one only made it a couple years and already looked terrible. Do it once do it right, cry once. I can't see paying $4k every few years for a quality finish. You can easy monstaliner for way less and have it last a life time.
