There really seems to be no rhyme or reason on why some have decal problems and others with similar/same models have no problem. My decals all looked great for 6 yrs. then the front and rear started peeling. Sides still look great after 8 yrs. Exact same trailer in storage near mine still looks good all around at same age. Others have reported peeling/cracking after only 2-3 years. And all over the country and in all environmental conditions. Mine being in TX sun and heat.
But at least Keystone provided replacement decals for free for me to install or pay to have installed.
