The carpet in my Cobra trailer is shedding badly. I would like to replace or cover it. Open to any ideas on how to remove the old carpet or can you just put some new material on top of the old? What material would be best? Soft felt, hard felt, carpet?

The carpet generally comes off surprisingly easy, I found. That's the best property of the original carpet. But it makes a powdery mess as you do so wear mask and probably gloves...
What is left behind is a bit of a sticky that I didn't care to remove. Instead I used loctite spray adhesive and a basic low pile outdoor carpet as the replacement. You will want to save the old pieces to use as a template.
