Hi Lynn
I replaced my awning rail grey strip last year on my motorhome.
As you say, it is not easy!!!
I found the best way is to use a hair dryer on about 10" or so on the plastic trim to heat it and soften it.
It can then be inserted into the groove using something like a flat head screw driver to push it in place. Put one side in first and then push the other side in with the screwdriver ( or flat something!!!!)
It will take a long time but I have not found a better way. Make sure you do not overheat, but trial and error is the best way.
By the time you read this, I expect you will have already done the job!
