car insurance rental coverage

Should I reduce my car insurance now that he has paid?
My truck is paid next month and am thinking of reducing my insurance coverage. If I like the comp and collision coverage for rental cars and my cousin goes from $ 84 per month to $ 48. Big savings. But it is too risky? My truck is 1997 Nissan a truck is in great shape.
Guess it comes down to how easy it would be to replace the car if you got in an accident without collision. It might be cheaper in the long run than just paying extra each month, instead of having to pay higher monthly payments and total coverage for a replacement vehicle. However, you must have though to yourself.
