I agree with bpounds; seems a bit light on the pin, so please weigh, or re-weigh, your rig, ready to camp. Also, how level are you? If you're more than a couple inches off-level (usually nose-high), you can experience chucking. Does this happen on all roads or just the ones you travel most frequently? Your length can have an effect in that you can develop a sort-of harmonic due to the distance between your truck and the FW axles. Speed can affect this, too, so speeding up/slowing down by even 1-2 mph, can change this.
