Sorry forgot to add the trailer has leaf spring suspension and no issues being towed by two other trucks loaded the same way. The combination of the softer rear suspension of the Ford ( sunk 1/2 again as much as the other two trucks) and the soft tires seem to be the culprit . I will try adjusting the hitch once more with the added tension on the levelers.

What configuration is you FX4 ( cab, suspension, bed length tires) ?

I can say that my truck was very "floaty" until I added my bags. IMO, the rear of these trucks is sprung very softly (for a nice unloaded ride). It sags a LOT with not a lot of weight on the back.

After I added the bags it really made the truck more confident feeling under load. Not only do the bags level the truck, they also have the same effect as adding a sway bar. The back of the truck has much less tendancy of being pushed to one side or another by the trailer when making turns, etc.

If I were pulling a trailer as much as you are, I'd do the bags (and a controller/compressor) for sure.

I put a set of Firestone Ride Rites with an Air Lift Wireless controller. It rocks.

Supercab with 5 1/2' bed. 20' tire option. It towed fine with the factory Pirelli Scorpion's but those have since worn out. Now it has a set of Nitto E range tires on it. There is a picture of it on the thread "Lets see some trucks with trailer pics!!!", post # 611. That's 500lbs on the tongue with a 6800lbs boat. Pulls it absolutely fine, no sway, although I don't go faster than 60-65 with it.

Once the truck gets past 550-600 lbs on the tongue is when the front end becomes light and I can see where a wd hitch would be beneficial.

Two things that will certainly improve how your trailer and consequently truck rides and tracks over bumps are radial trailer tires and torsion suspension. The difference is night and day.

Since the trailer has new tires, the radials will have to wait a while and since the trailer is fairly new, torsion suspension is out of the question. with the adjustments it is miles better than it was.

Air lift air bags for $239 is the next addition and since I can trade a customer a gun to install them it will be a nice improvement for towing and bringing home inventory. The tires I had them put on from the old truck are much better than stock but I still will most likely replace them as well.

I would like to thank everyone for their help in this matter!

Don't forget to update the thread after the airbag install. Good luck!
