i do not think so, because it would contradict Tee, runaway story, what ever she did during the time she dumped his body was most likely done in an attempt to support her statement if he was found quickly. Undressing G would mean people
would question runaway if he was discovered.
people still seem to stick on the idea of Tee leaving AS's truck at the rental place, we did received clarification that she stated her car not the truck.
seeing the red truck actually was AS's vehicle, logic suggests that he would expect and want it available for him to use upon returning home, had it not been that would also have been a massive red flag.
Had G been sick or other in the back she had preslpained he was ill, so hiding it wasn't necessary, even if the back smelt bad she felt she had provided a suitable story to cover that angle.
I highly doubt she did anything inside the truck to leave extra, difficult or impossible to justify evidence.
AS getting home and finding his truck missing would have been a problem for her. IMO
