I removed and replaced the large front decal and two medium size ones (one on each side). The job was not that hard with a hair drier and a 1 1/2" putty knife ( After getting the peeling started with the putty knife I peeled mainly with my fingers). I tried a heat gun early on and it didn't do as well as the hair drier. The front one took about 3 hours and was approx. 30" x 6'-0". It was the last one and I was more experienced by the time I got to it. The ones on the side were 12" x 5'-0" and took about 4 hours each. After removal I cleaned the areas with Goo Gone and then cleaned it again twice with 91% rubbing alcohol as the decal instructions say not to use citric cleaners as the final cleaner. Applying the new ones was not hard at all it just requires two people and watch a couple of You Tube how to's. By the way mine was on a Keystone Outback, I see yours is a Keystone also.
