2015 3010ds shower door bottom seal
Ours is a '14 2860 and I replaced mine with the "T" shape and I got it on Amazon
There are shower door suppliers that sell all the different shapes
The top of the "T" slides into the track on mine like the nubs of the "L" and the bottom of the "T" is longer so it covers the gap better and keeps water in.
I bought from CRL,and it's a better quality
I did modify it with a razor knife to fit perfectly.
Also I used clear silicone caulk along the bottom of the door on both sides
We are leak free now but the factory set up was causing water damage from leakage,that fortunately I nipped in the bud.
I never saw a Hearse towing a Trailer
