The mod loads up in the store on my end, it has to be a mod conflict. as for interrior cam, i can see the mod realistic cab view being the cause of it flipping, it works fine for me
I finally figured out the flipped camera issue. In general settings if "Dynamic Vehicle Camera" is Off the view is upside down. When turned On the view is correct. I generally play with it off why I was having issue. Other than that everything works great.
