RV Fender Skirt Measurement Guide: ICON Single, Tandem & Triple Axle

Choosing a new RV fender skirt starts with the original skirt's axle layout, exact outline and measurements, not simply the trailer brand. ICON uses FS design numbers to identify shapes. This guide compares single-, tandem- and triple-axle examples and links each part to its product listing.

Measure your original fender skirt

Simplified illustration for orientation; not a scaled profile or hole-location drawing.

A — Top lengthCentre to centre of the top holes indicated in the manufacturer drawing
B — Wheel wellBottom of outside leg to highest point of a wheel opening
C — HeightLowest outside-leg point to highest point overall
D — Outside legSide edge of skirt to inside edge of its outside leg
E — Inside legWidest point at bottom of inner leg, if present
F — LengthEnd to end, using the longest points of the entire skirt
  1. Count the wheel openings and record whether the old skirt is a one-, two- or three-axle style.
  2. Measure full length (F) and overall height (C) at their widest points.
  3. Record mounting-hole centres (A), wheel-well rise (B), outside leg (D) and centre leg (E) where applicable.
  4. Compare the complete outline, leg ends, colour and exact ICON part number. Similar dimensions do not prove that mounting holes line up.

For the full set of measurement positions, refer to ICON's fender skirt measurement sheet (PDF).

Dimensions alone are not enough

Different RVs can share a similar skirt length but have different wheel-arch curves, fastening points or leg ends. Use dimensions to shortlist, then compare the whole shape.
