Hooked up the trailer to our expedition for the first time and did a 25 mile test run on the interstate. This is the first time I towed anything big with the Expy. I usually use my F250, HUGE difference. Towing a 30ft trailer with an Expy difinetly has a pucker factor. There was a bit of a bounce. I was able to maintain my lane, but that surge / bounce effect leaves me feeling uneasy. Is that normal when towing a TT with a half ton vehicle. The back of the truck saged a bit, and nose was up slightly. I know the expys always sag a bit, even with the WD hitch because of the independent rear suspension. Do I need to crank up the weight distribution bars by one more link on the chain? I'm on the 5th link now.

The settings will most certainly be different.You need to go thru the setup procedure again for the EXP. If you are not going to get another hitch, then record the setups for both TVs so you can quickly reset it to what TV you will be using.

Well, I don't claim to be an expert, but if the back sags, it clearly means that the trailer is taking weight off the TV's front axle relative to the back axle, and that WILL cause "directional instability."

The hitch was never set up for the F250. I bought the trailer off my cousin who also had an Expy. The dealer set the hitch up for her truck. When I bought the trailer she gave me the hitch with it. Her Expy is a '12, mine is a '07 virtually the same vehicle.

I use a 2008 navigator without air suspension to pull a 35 foot 7000lb passport. I use a reese dual cam and once properly set, the truck returns to unhitched front height and the rear only sags 3/4 inch. A good hitch with sway control properly adjusted makes a huge difference.

And my setup is an '04 Expy pulling a 6200# Kodiak using the Reese DC. Same as Svichera, very little rear sag (1/2" to 3/4"), front is back even with 800# bars, and a tongue weight of 820#.edit: this is what happens when you cross-read threads... I removed a section; I still think your tongue weight may not be in the 12%-15% range, causing the driving feel.
