New shocks needed?

I'm looking for opinions on whether or not new shocks are needed. I have a 2009 GMC Sierra 1500 Crew Cab. I'm not sure if shocks/struts were replaced previously as I just purchased this truck 4 months ago. When I had my truck bed loaded for camping last weekend with 4 bikes, a kayak and some fire wood, the back lowered to where the bad and front were level, normally the back sits around 1 inch higher. I also noticed a little "wave" action when I go over bigger bumps in the road. Does it sound like my shocks/struts should be replaced?

At the age of the truck and not knowing the mileage, I would say, it could not hurt. I changed the front shocks on my RV at 20000 miles and it made a difference!

Stand in front of the truck and step up on the bumper .

Do it in sequence to help the front to go up&down.

When you stop off/on the truck should stop in the next rebound.

Since it does no harm , use the technique at a dealer or friend with a similar truck with no miles.

The 1 inch drop seems ok but our roads in MI will be a challenge to your shocks if you change them or not. Inspect them, looking for leakage or other obvious problems. Rocking sounds like porposing (spelling) may not be present when unloaded. Can be induced by the repetitive seams in pavement especially on highway. Changing shocks to a higher performance design both front and rear improved mine and was relatively inexpensive auto repair.

Rear shocks don't affect ride height...that is a spring issue.
