question on towing my featherlite-hitch weight?

I have a new 2013 ram 1500 truck... 5.7 hemi. states it can tow 8500 pounds.. my 2011 jayco featherlite 17 c is way way under this weight... according to yellow sticker on door w/propaine it weights in at 2950 pounds.. im not worried about pulling it. im wondering about the cargo weight for my truck.. with people and cargo in bed and tongue weight of hitch it cant exeed 1500 pounds...im going on my first trip next week.. gonna have 5 people In truck.. figure we weight roughly 750 pounds just in passangers... and according to jayco brochure the hitch weight of my camper is a whopping 475 pounds dry?? can this be correct for a 2950 pound camper? so this puts me at 1225 pounds already.. not much room to add any cargo to bed of truck(wood,coolers,bikes) anything I may need... plus the camper only has a ccc of around 475 pounds, so im really limited on what I can store in camper.
question is, does 475 pounds sound correct for dry hitch for this camper? and if so, should I have my wife drive up with the other passangers in another car? its about 60 mile trip. I hate to waste two cars and gas but not sure how to do this... btw, we will be way under towing capacity of ram truck and under the GCWR...its just the 1500 pound payload im worried about which I think has to include the hitch weight..thank you
