If by outside moldings, you are referring to the vertical seams of your RV, then the Dicor 551LSW would work for that. For sealing around your windows, however, I would suggest using the Dap 08646. Dap also makes a sealant that works for windows, doors, molding, baseboards, siding, trim, pipes, vents, ducts, butt joints, corner joints, above ground foundations, and flashing. I will link these below for you.
