I think it depends a lot upon the tow Vehicle as to how much tongue weight would be considered safe. Our tongue weight with camper loaded will be close to 500 lbs. With the model 6503 almost everything is located in front of axle, hot water tank, propane tank, fresh water tank and battery and now with ours the spare tire too. We only carry about 10 to 15 gallons of fresh water when traveling. With a SUV that may be to much tongue weight but with our truck a Ram 1500 it works out good for us. We use the Equalizer 4 point sway control WDH, and we have no problem with sway or bouncing.
