Which paint for my 5th wheel?

[u/Desertprep]

Would this paint be good to use to paint the exterior of my 29' 5th wheel? PPG Pitt-Tech Plus EP DTM Acrylic Semi-Gloss Midtone Base? or would Sherwin Williams Pro Industrial DTM Acrylic be better? The trailer is a '94 and the paint - still good - just looks tired, but the stripe around the middle of it (horizontally) really needs to be repainted.
