Shocks for my 08'

I'm getting some wheel bouncing after hitting obsatcles on the road.
I think its time for new shocks, the truck has the OEMs in it and I wonder how the quality of them is seeing how they are not giving me the ride anymore.

Anyway I only use my truck ON-ROAD. I do haul a pretty heavy boat and I think that killed the rears.

So what it a decent shock I should put on her.
Nothing extreme, just a good quality that gives a good ride.

Any help is appreciated.
