I disabled Bluetooth on my way to work today and it worked.  I'm not ready to call it fixed, but I am definitely hopeful and it's a great start.  Something interesting did happen with my phone though.  With Bluetooth and Wifi off my phone is able to communicate with my watch still.  That is either weird or I'm learning something new.  LOL

Awesome! Thanks for the update!
To be fair, you don't have to disable bluetooth, just forget the connection to your truck on your iPhone and it won't connect automatically - good thing to do if you're using Apple Car Play.
WiFi shouldn't affect any of the issues you've experienced.
And, yes, the Apple Watch will still connect even with bluetooth off as long as there is a WiFi connection it can fall back on - same WiFi as your iPhone - however, you will not have a watch connection without either bluetooth or a common WiFi connection.
