Sway issues with TH

We are new owners of a Adrenaline TH,25QH tried maiden trip and had dangerous sway. Above 45mph got scary. Trailer loaded with 2 light bikes was at 8400#, (did not get tongue weight loaded). Bikes weigh 800# combined, larger was full forward over the axles. Called Coachman and they were helpful, mentioned they have had to weld plate steel on the A frame of some trailers to get adequate tongue weight.

Dry weight is 7326#, I bought a tongue scale, dry is about 770# which Coachman says is about average. My question is - virtually all the cargo (toy)space is axles back - how can we carry anything and keep our tongue weight high enough?
Bought 300# of sand and shifted everything up front, still scary so we turned around and dropped it at home. Even bought the Equa-l-izer, to replace the dealer installed E2 12000# WD/sway control hitch while on the road, helped marginally.

TV is a 2016 F150 with ECO, supercrew shortbox. Had plenty of power, was lightly loaded, just my wife and I and a few suitcases.
Frustrated, as we bought the truck specifically for this, after advice from RV dealers. Do I need to design a ballast system for the tongue?
I plan on capturing various tongue weights as soon as I can, loaded, unloaded,etc.I'm assuming it is primarily a tongue weight issue? Any advice is appreciated!
  • You need more weight up front. I had the same problem years ago. Up front I had a couch and underneath was a storage area. (Empty) Was told to add maybe 100 pounds under the front couch. Worked. No more sway
  • Just going by the spec sheet numbers, you've only got about 11 and a half percent of the trailer weight on the tongue. Now you put 800 pounds in the back of the trailer and you're going to have serious problems. You might consider moving everything you can to the front bedroom while you are Towing and putting one of those bikes in the bed of the pickup truck. When you've done everything you can, head to a cat scale. There are many threads that will teach you how to weigh your setup.

    And no need to thank your dealer for his advice. A long bed F250 would have been a better match for what I believe will always be a difficult situation. We had a front load toy hauler that gave us the opposite problem but never did have a sway problem. And the dually really didn't give a hoot!
  • Sounds like Coachman poorly designed the weight distribution. And why the RV salesman would recommend a 1/2 ton, I don't know. I mean, if you already owned it, that's one thing, but to recommend you go buy one for this trailer? Engine power is only part of it. Brakes, wheel base and weight of a heaver truck figure in there to control the load. Hope you get it worked out.
