  1. 1

    Remove your present wall covering in your travel trailer. Note that if it is manufacturer installed, it will be custom wall panelling made for your particular motorhome. Previously remodelled travel trailers may use other materials. Use a crowbar or other pry bar to pull all the panelling off. Remove any remaining staples or nails as well.

  2. 2

    Inspect the wall interior while your panelling is removed. Seal any visible water leaks, which may appear around windows or doors.

  3. 3

    Replace any damaged or old foam insulation that lies beneath the wall panelling in your now-exposed stud walls. Use either similar styrofoam insulatio, or even expanding foam insulation, especially around windows. Cut styrofoam to size, spread with adhesive and fit into place. Spray foam into area, alternately, following the product instructions. Avoid overfilling with expanding foam; cut away excess, if needed, after it dries.

  4. 4

    Measure your wall lengths and purchase new RV interior panelling accordingly. Divide your measurements by panel dimensions to estimate what you will need, buying an extra sheet or two to allow for mistakes.

  5. 5

    Spread adhesive on the back of each wall panelling then set into place against the wall. Determine where your studs are, noting approximately as you put a panel into place and pressing with your hand to feel the harder areas. Nail panelling into place at the studs to secure further.

  6. 6

    Measure areas where you cannot use a full sheet of panelling. Mark any objects such as windows or receptacles on the back of your panelling, then use a circular saw to cut to fit. Continue until interior is complete.

Tips and warnings

  • Purchase interior panelling from your travel trailer manufacturer for a perfect fit. See Resources for more information.
  • Always take safety precautions when working with saws. Wear goggles and do not touch blades while cutting.
