Seam planning for oversized panels
RV sides are taller and longer than any single run of 60-inch film, so seams are unavoidable. Hide horizontal seams along existing body swage lines and overlap them downward (like roof shingles) so water sheds away from the edge. Map every seam before the first panel goes on.
Film footage and crew size
A full Class A motorhome can consume 120-260 linear feet of film (400-900 sq ft) and 40-120 labor hours. This is a multi-installer, multi-day job - staging, scaffolding and a controlled-temperature bay are part of the quote, not afterthoughts.
Slide-outs and flex
Wrap slide-outs in the extended position and relieve film at the rubber seals so the mechanism still retracts without dragging the edge. Large flat fiberglass panels also flex in transit, so use cast film and post-heat the edges to prevent seasonal lifting.
