I've posted on here before with same problem now need advice. I have visited old posts not really any help.I had 2wd dually measured hitch bought megacab 3500 put hitch in receiver adjusted hitch too same height.the mega dropped 6 or so inches dually only 2" or so. anyway second trip on hwy felt very unsafe. trailer was little higher in front than back . So correct me if im wrong I plan on leveling trailer measure tongue and adjust hitch again . I use wd bars tongue weight alot i guess 900 to 1100. the travel trailer weights loaded 9400lb

 

webbfoot,
I am sure there is a question in that post some where. I just don't see it.

I run my trailers level. If that is what your asking? If I run it high in the front the trailer will sway.

 

I tow level also. If you tow with the front of the trailer up to high it will tow terrible and have all kind of issues. I would re-adjust.

 

My trailer weighs just over 10K lbs. and it's adjusted level. No sway problems at all. Get it level.

 

Sounds like your ball is to high if your truck is dropping 6". But without seeing the rig its hard to say.

 

I don't see how you can drop 6". Assuming that you did, how can the trailer still be high?

 

May want to increase your tongue weight in #50-100 lb incrument or decrease rear of trailer the same amount. My boat weights about #6500 lbs and the tongue is #630 or so. If the gas is full in the boat (70 gallons, tank near the back) the rig wants to over steer a little. I like to keep my boat less than a 1/4 tank for towing. The 200-300 lbs makes a difference for me The gas tank for the boat is about 2 feet behind the 2nd axle. I am working from memory here because my boat is in storage and it's freezing rain now and the season will not start for me till April .
