I put a fiberglass hard cover and it has drawbacks but I have no regrets..

If I had to do it over I would spray the bed with LINE X first..Then a bedrug which I have now and love it...Then the tonneau of your choice..

1972 Road Runner / GTX 440 4spd Dana 3.54 Just about to turn 26K original miles..

A boat, a GMC truck, some Craftsman Tools, LOTS of Zombie Protection, and a few Goldfish..

If you love someone set them free..
If they come back it means nobody else wanted them either..!!
