I just finished up doing some pretty major changes to the interior of my single cab LMM. For some reason, GM decided to limit the available options on those trucks, but thanks to a good friend of mine, we were able to add almost everything you could possibly get on one of these trucks. The truck came out of the factory as a base model work truck with rubber floor, manual windows and locks, single zone manual hvac, etc. It now has power windows and locks, full floor center console, digital dual zone hvac, keyless entry with remote start, steering wheel radio controls, and dic buttons. It still has the manual tow mirrors, but I'm working on finding a good set of power fold regular mirrors. Now I need to get started on my short bed conversion.
