RV Armor Inc roof repair?

The camper I am looking to buy has had this service done by rv roof.com. I inspected the roof and it appears to be VERY high quality. I used to spray in truck bed liners for a living and this particular liner looks like it is applied similarly. The liner is thick and cut with a wire tape for a clean edge. It covers all the joints where the seams on top meet. I have compared this with my father in law's travel trailer re-roof which they used a rubber sheet for and there is no comparison. His was 1200 and the other trailer I looked at with the rvroof spray job was 3700. It could be argued that you could purchase 3 standard rubber roofs for the price of 1 spray on roof. That being said the spray on roof is supposed to be good for at least 20 years. If I had the money, after seeing the roof armor roof first hand, that would be my choice hands down. The quality of the roof is just amazing and I'm surprised there isn't more publicity about it. If I was buying an rv that I planned on keeping forever that would be my choice. If I was planning on upgrading in 2 or 3 years, I would pick the standard replacement.
