My suspicion is that it might be a ground problem. Keystone sent me a brand new turn signal to try replacing it, but I found that the original signal is glued in place. How do I go about breaking the glue seal without damaging something?
Man, do I have a bunch of issues. Fortunately they are relatively small in the big scheme of things, but I’m trying to get the new bugs out. Thank you in advance for anyone’s suggestions and help with this matter.

You're guess at a poor ground is a very probable cause. I'm guessing it's flashing rapidly when connected to the tv because the truck's systems see a "defective" turn lamp and flashes rapidly to warn you.
The "glue" you speak of, is that on the tail lamp itself? You are most likely seeing silicone sealant. Just carefully peal it away with a plastic putty knife or a cut it with a razor knife. Once the lense is off check the lamp in the socket (the outside "barrel" of the bulb fits in a copper socket, this is the ground. Any discoloration, green tinge, is corrosion. Since it sounds like the dealer gave you a new tail lamp assembly just replace it.
Make sure the sealant behind the unit is intact (typically butyl tape) and apply a small bead of silicone back on the top of the fixture.
