I wear and have added some seat belts in any of my MVs that have a cab. I just think that in a crash I am going to hit something in the cab. I do not wear or install seatbelts in Jeeps with no ROP. If I have an accident in one of them I know I am going to be ejected. I am a retired LEO and have seen many accidents and have formed my own opinion and am not giving any advice.
