Key Takeaways

  • Most Keystone RV models — including the Cougar, Montana, Alpine, Bullet, Sprinter, and Passport — are factory-fitted with Lippert-sourced awning systems, many of which share components originally engineered by Carefree of Colorado or Dometic.
  • Fabric replacement is the most common Keystone RV awning repair and can be completed by experienced DIYers; roller tube removal, spring tension adjustment, and motor replacement require additional caution and are often best left to certified technicians.
  • Correct fabric measurement is critical — owners should measure the roller tube length, not the visible canopy span, to determine the correct replacement fabric width.
  • Power awning motor faults on Keystone fifth wheels frequently stem from the Lippert Solera control board or wiring harness rather than the motor itself; diagnosis should precede any parts replacement.
  • RVIA-certified service professionals recommend de-tensioning the awning spring before removing the roller tube — failure to do so can result in sudden, forceful roller rotation and serious injury.

What Awning Systems Do Keystone RVs Use?

According to RollingRambles’ certified technicians, the overwhelming majority of Keystone RV models ship from the Goshen, Indiana factory with awning assemblies sourced through Lippert Components, Inc. (LCI). Lippert acquired the Carefree of Colorado awning line, and many current Keystone units — particularly Montana 3000-series fifth wheels, Cougar half-tons, and Alpine luxury fifth wheels — use the Lippert Solera manual or power awning platform. Older Bullet and Passport travel trailers may carry legacy Dometic A&E hardware that shares dimensional standards with current Solera components.

Keystone’s published owner documentation references Lippert service bulletin standards for awning torque specifications and hardware service intervals. Owners should locate the awning brand label on the end cap before ordering any replacement parts, as cross-brand substitution — even within Lippert’s own product family — can result in incompatible roller diameter or fabric attachment rail dimensions.

How Do You Replace Keystone RV Awning Fabric?

Fabric replacement is the most frequently requested Keystone RV awning replacement service. RollingRambles’ RV maintenance team outlines the following procedure based on Lippert Solera service documentation and field-verified technician experience.

Step 1 — Measure Before You Order

Owners must measure the roller tube length, not the deployed canopy width. The replacement fabric should be ordered approximately 10–12 inches shorter than the roller tube measurement to account for the hemmed ends and the travel bar pocket. For example, a 19-foot roller tube typically accepts a fabric labeled “18 FT” with an actual fabric dimension of approximately 17’2″.

Step 2 — De-Tension the Spring

⚠ Safety-Critical Step: RVIA-certified service professionals strongly caution that the awning spring must be fully de-tensioned before roller tube removal. On Lippert Solera systems, this is accomplished by extending the awning fully, inserting a winding bar into the roller end cap, and counting the spring winds as tension is released — typically 5 to 7 full rotations on standard 15–21-foot assemblies. The roller tube must be secured with locking clamps before the winding bar is removed. Failure to follow this procedure has caused documented injuries. RollingRambles recommends professional assistance for this step if owners have not performed it previously.

Step 3 — Remove the Roller Tube

  1. With the awning fully extended and the spring de-tensioned, support the roller tube with a padded ladder or a dedicated roller cradle support.
  2. Remove the end cap retaining screws (typically #10-32 Phillips or hex-head fasteners) from both end caps.
  3. Slide the roller tube free of the mounting brackets and lower it to a clean, flat work surface.
  4. Remove the old fabric by locating the aluminum extrusion channel running the length of the tube and sliding the fabric’s hem rail out of the channel.

Step 4 — Install the Replacement Fabric

  1. Feed the new fabric’s hem rail into the roller tube extrusion channel, starting at the center and working outward to both ends to prevent bunching.
  2. Seat the travel bar hem into the lower rafter rail channel at the awning arms.
  3. Reinstall the roller tube, re-tension the spring to the original wind count, and test deployment through the full range of motion before finalizing hardware torque.
  4. Tighten end cap fasteners to manufacturer specification — Lippert service documentation specifies 15–20 in-lbs for #10-32 end cap screws to avoid stripping the aluminum housing.

How Do You Service the Roller Tube, End Caps, and Hardware?

According to RollingRambles’ RV maintenance team, end cap and hardware service is often overlooked during fabric replacement but is critical to long-term awning reliability on Keystone models. The roller cradle support brackets — the plastic or nylon saddles that cradle the roller tube at the mounting points — are a known wear item on Lippert Solera fifth wheel awnings. Cracked or deformed cradle supports allow the roller tube to shift laterally during operation, accelerating fabric edge wear and causing uneven rolling.

Door awning track assemblies on Keystone models also use small roller wheels inside the fabric track channel. These wheels guide the fabric edge during deployment and retraction; worn or flat-spotted rollers cause the door awning fabric to bind or tear at the hem. Lippert part reference 901032 is the compatible roller wheel for Carefree-track door awning systems found on many Keystone trailers.

How Do You Diagnose and Replace a Power Awning Motor on a Keystone RV?

Power awning motor issues are among the most reported service concerns on Keystone Montana and Alpine fifth wheels equipped with the Lippert Solera Power awning system. RollingRambles’ certified technicians note that the fault is more often located in the Lippert Solera control board or the 12V wiring harness than in the motor unit itself. Before ordering a replacement motor, technicians recommend the following diagnostic sequence:

  1. Verify 12V DC supply voltage at the motor harness connector using a multimeter — acceptable range is 11.5V–13.8V with the RV plugged in or the battery system active.
  2. Check for fault codes on the Lippert OneControl or Solera wall switch display, if equipped. Error code E2 typically indicates a motor overcurrent condition; E4 indicates a Hall sensor fault.
  3. Inspect the harness connector at the motor for corrosion or pushed-back pins — a common failure point on awnings exposed to road spray.
  4. If voltage and wiring check out, the motor assembly — Lippert part number 360289 for most Solera Power awnings — can be unbolted from the roller tube end cap (four M6 hex bolts) and replaced as a unit.

Important: Motor replacement on power awnings involves stored spring tension and live 12V wiring. RollingRambles strongly recommends that owners without prior awning motor service experience defer this repair to an RVIA-certified technician or an authorized Lippert service center.

Recommended Parts & Tools for Keystone RV Awning Replacement

Based on technician recommendations and verified compatibility, the following parts meet RollingRambles’ standards for Keystone RV awning service:

Replacement Awning Fabrics

For Keystone models in the 16–18-foot awning range, RollingRambles’ maintenance team recommends heavy-duty 19.5oz vinyl fabrics with heat-sealed seams and UPF 50+ UV resistance ��� the same weight class specified in Lippert’s replacement fabric guidelines for full-time use awnings.
