Rack Mounted Shower Tent Installation Guide

This comprehensive guide provides detailed step-by-step instructions for a smooth installation, safety considerations, troubleshooting tips, and maintenance advice to ensure your shower tent is reliable for your camping adventures.

Upgrade your Opus OP4 off-road camper with the rack mounted shower tent featuring the Iron Man tent! This comprehensive guide provides detailed step-by-step instructions for a smooth installation, safety considerations, troubleshooting tips, and maintenance advice to ensure your shower tent is reliable for your camping adventures. Based on the "Rack Mount Shower Tent Installation SOP_RMSTIV0920-1.pdf" (issue RMSTIV0920, 14 pages), this article covers the process for the OP4 model, divided into drilling holes in the roof rack, installing the bracket to the Iron Man tent, and mounting the assembly to the roof rack. The installation takes about 7 minutes with basic tools and is suitable for DIY enthusiasts. Always read the full instructions before starting. Let’s get your outdoor shower set up!

Before You Begin

  • Safety Checks: Work in a well-lit, flat area with the camper parked on level ground. Wear safety glasses, gloves, and ear protection to guard against metal shavings or noise from drilling. Disconnect any propane or water sources to avoid leaks.
  • Tools Needed: 1/4” hard metal cobalt drill bit (for drilling), wrench set (for bolts and nuts), Loctite glue (for securing threads), and a helper for lifting the shower tent (approximately 15-20 lbs).
  • Parts Supplied with the Kit:
    • 1 x Mounting Bracket (sturdy metal for support).
    • 1 x Iron Man Tent (waterproof enclosure for the shower).
    • 3 x M6 x 50 mm Bolts (for securing the tent to the bracket).
    • 1 x Slab Base Nut (for base mounting).
    • 1 x M6 x 16mm Bolt (for additional fastening).
    • 4 x M6 Lock Nuts (for vibration-resistant securing).
    • 3 x Lock Washers (to prevent loosening).
    • 2 x M8 Oversized Washers (for distributed load).
    • 1 x 5/16” Washer (for specific bolt).
    • 1 x M8 Nut (for heavy-duty fastening).
    • 1 x M6 Nut (for final assembly).
  • Preparation: Verify all parts are present and undamaged. Clean the roof rack and tent surfaces. The RMSB is designed for the OP4’s roof rack—ensure your rack is rated for the tent’s weight and check for compatibility with other accessories.
  • Warnings: Do not install while the camper is moving or on uneven ground. Ensure all connections are leak-proof to avoid gas or water hazards. This is a standard operating procedure for the OP4 model—consult your dealer for other models.

Step-by-Step Installation Guide

The process is divided into three main sections as per the manual: drilling holes in the roof rack, installing the bracket to the Iron Man tent, and mounting the assembly to the roof rack. Follow in order for best results.

Step 1: Drill Holes in the Roof Rack

  • Positioning: Place the mounting bracket on the roof rack, aligning it with the rear folding arm. Use the bracket as a template to mark the hole locations (typically 3-4 holes per side for stability).
  • Drilling: Use the 1/4” hard metal cobalt drill bit to drill through the marked spots on the roof rack. Drill slowly to avoid overheating the bit—apply cutting oil if needed for smoother drilling.
  • Deburring: Remove any burrs or sharp edges from the drilled holes with a file or deburring tool to prevent injury or damage to the tent fabric.
  • Troubleshooting: If the drill bit slips, use a center punch to mark the spots precisely. If the rack metal is too hard, use a slower speed or replace the bit if dull.

Step 2: Install the Bracket to the Iron Man Tent

  • Bracket Placement: Place the mounting bracket on the base of the Iron Man tent, aligning the holes with the tent’s pre-marked mounting points (typically on the bottom frame).
  • Securing: Insert the M6 x 50 mm bolts through the bracket and tent base, adding lock washers and M6 lock nuts. Tighten with a wrench, applying Loctite glue to the threads for vibration resistance.
  • Additional Fastening: Use the M6 x 16mm bolt, M8 oversized washers, and M8 nut for the center support, ensuring even distribution.
  • Troubleshooting: If holes don’t align, check for manufacturing variance—gently enlarge with a file if needed, but avoid over-drilling to maintain strength.

Step 3: Mount the Assembled Bracket and Shower Tent to the Roof Rack

  • Placement: Lift the assembled bracket and Iron Man tent onto the roof rack, aligning with the drilled holes. Position so the door opening side faces conveniently for use.
  • Securing: Insert the remaining bolts (e.g., M6 x 50 mm) through the bracket, roof rack, and slab base nut. Add M5 washers and M5 x 0.8” hex nuts from underneath, tightening until secure.
  • Final Check: Tug on the assembly to ensure it’s stable—there should be no movement. Apply Loctite to all nuts for long-term hold.
  • Troubleshooting: If the assembly wobbles, add extra washers for padding or re-tighten bolts. If the rack bends, stop and contact Opus for reinforcement options.

Troubleshooting Common Issues

  • Drilling Problems?
    • Cause: Dull bit or hard metal.
    • Fix: Use a fresh cobalt bit and apply pressure steadily. If the rack warps, stop and consult a dealer.
    • Prevention: Drill pilot holes first for precision.
  • Bracket Misalignment?
    • Cause: Uneven tent base or incorrect placement.
    • Fix: Realign the holes, using a clamp to hold in place before bolting.
    • Prevention: Measure twice before drilling.
  • Loose Fittings During Use?
    • Cause: Vibration from towing.
    • Fix: Re-tighten with a wrench and add more Loctite; replace lock nuts if worn.
    • Prevention: Check after 50/500 miles.
  • Tent Leaks or Shifts?
    • Cause: Poor mounting or weather damage.
    • Fix: Inspect seals and re-mount if shifted; patch leaks with waterproof tape.
    • Prevention: Secure tightly and cover during storage.

Maintenance and Care

  • Regular Inspection: Check mounting bolts and nuts monthly for looseness, especially after rough trails. Re-apply Loctite annually to threads.
  • Cleaning: Wipe the Iron Man tent with a soft cloth and mild soap after each use; avoid harsh chemicals. Clean the bracket with a rust-inhibitor spray quarterly to prevent corrosion.
  • Seasonal Prep: Before winter, remove the tent if storing outdoors to avoid snow load. Inspect for UV damage annually and replace fabric if faded.
  • Storage: Fold the tent neatly and store in a dry place; cover the bracket on the rack with a tarp to protect from elements.

Safety Tips and Considerations

  • General Safety: Wear gloves and glasses during installation to avoid cuts from metal edges. Work on level ground with the handbrake engaged.

  • Gas and Water Hazards: Test all quick-connects with soapy water (bubbles indicate leaks)—do not use open flames to test. Ensure proper grounding for electrical tools.

  • Warranty Note: Improper installation (e.g., over-drilling) may void warranty—follow steps carefully and use supplied hardware.

  • Environmental Tips: Install in a ventilated area to avoid inhaling dust from drilling. Dispose of old parts responsibly.
