Here are all the "mods" I have done so far (some may not be considered "mods"):
1. replaced antenna with a short antenna purchased from AutoZone (no reduced reception noticed)
2. Line-X spray-in bedliner
3. rear seat armrest/drink holder installed (TSI 30011 Bench Seat Clutter Catcher - purchased off Amazon)
4. Gator rollup soft tonneau cover
5. towing receiver package installed
6. got and using the TopGo cellphone holder (love it and holds phone secure at the perfect height)
7. GM Factory floorliners for front and back (courtesy of my GM Rewards points - love them)
Looking at potentially adding:
1. BDTrims rear "Chevrolet" inserts, and
2. Full rear window decal of US Flag to show my support and patriotism for this great country
Last week I had the first oil change/tire rotation/service done. Also had 3 recalls done. Then yesterday I got another recall notice in the mail about the brake system. Frustrating, but glad this is on GM and not me.
I'm loving my truck. I'd love to be able to clean it up, but it won't stop raining long enough down here in the South to give me time to do it.
