Having an RV, whether for use as a home or for vacation, is a huge benefit. However, having awnings improves the experience! Imagine relaxing in a chair outside your parked RV without getting sunburnt and appreciating a good view.

This pleasant experience, however, may be ruined if your Dometic awning roller tube wears out or becomes damaged. You may need to change awning on your camper or, if possible, repair it.

In this article, we’ll show you how to replace an RV awning roller tube and keep your RV running smoothly.

Step-by-Step: RV Awning Roller Tube Replacement


Before you do anything to your awning tube, you must decide whether you want to do RV awning roller tube repair or replacement. If you identify that the damage or status of your awning tube cannot be fixed by a repair at all, your only best option is to change it to a new one.

If your RV awning roller tube bent, you have no other choice but to change it. The following steps will help you to DIY awning roller tube replacement:

What to prepare:

  • Tape measure
  • Electric drill
  • Bolt extractor tip
  • Screwdriver
  • Rag
  • Silicone spray
  • A new awning roller tube
  • Electrical or masking tape
  • Ladder
  • Vise grips

Step 1: Buy the exact model of your camper awning roller tube

Check for the model and brand of your awning roller tube. If you have a Dometic awning, it is better to buy it directly in their store than any other dealer.

If you don’t know the model and brand of your awning, measure the tube from the RV awning roller tube end cap to the other using a tape measure. Later in this article, we discussed how to properly measure a roller tube.

With that, you can look up the measurements online to see which model fits your used RV awning roller tube.

Step 2: Unscrew the bolts holding the awning to the RV


First, you will want to remove the broken and old awning roller tube for the place of a new one:

  • Roll up the awning. Then, get a drill and a bolt extractor tip to unscrew the two bolts on each side of the roller tube.
  • Use a drill or a screwdriver to take off the screws holding the fabric on the long, horizontal metal plate.
  • Remove the awning arms out the bracket and extend them to the ground.
  • Pull the fabric down. You may use a ladder and ask someone to hold the other side as you do this.

Step 3: Take off your awning roller tube


Put a rag on the other end or you can also try to place an electrical or masking tape. This prevention will help not to scratch your RV side.

  • Now, turn the shaft by using the vise grips Make a mental note of how many times you must uncoil the torsion spring before you can rewind it with the same frequency.
  • Using an electric drill or a screwdriver, you can remove the bolts attached to the end cap. Once the spring hampers, you can now take the end cap off.
  • Remove the roller tube’s spring assembly by pulling it out. Note as well the location of the valence and awning in the rails.
  • Drag the valence out, followed by the tube from the fabric. If the fabric is stuck in the tube, ask someone to get on a ladder to pull it off until it smoothly slides out. Ask for assistance in removing the tube from the RV, and make sure you have enough space around you.
  • Then, place the awning tube on the floor.

Step 4: Replacement RV awning roller tube


First of all, make sure you get a silicone spray and use it on the new roller tube for RV awning tube replacement. From this, the fabric and valence slide in easily.

  • As it’s ready, slip the roller tube on the fabric.
  • Reinstall the spring assembly and end cap to their original positions.
  • Secure the end cap with the bolts using either a drill or screwdriver
  • Reattach the torsion spring in the same number of unwinding.
