Weight Distributing Hitch setup

Wanted to get vehicle specific info on this subject. I have a 2007 Jayco 19H TT that we will be taking on a 14 day road trip in June/July, and typically take quite a few trips per year (had a new daughter in December so our camping is slow right now). I have been towing it with my CM with Airlifts and a Toytec AAL without any sagging issues but have decided that the benefits in an emergency situation make the WDH worth purchasing. Trailer has a GVWR of 4550#, with a 15% TW that would give me around 683# TW without anything in the bed when fully loaded. I am looking at Camco WDH's with 800# bars and 1000# bars. The 1000# bars are about $40 less and have more wiggle room, but are they too much for this setup? Can I jump up to the 1000# bars or stick with the 800# bars?

If I were to guess, mine is squatting about 3/4 to 1" or so...2 1/2 sounds like a lot. How many links do you have hanging? What is the height of the ball on level ground? What about the toung on level ground. I know I have mine almost lined up before hook up on level ground.
hey guys how much should the rear end be squatting using the dual cam system..mine drops more than 2 1/2 inches. and the front about 1/2 this normal or should i tilt the bars down more to get more leverage..if i do will i squat less in rear?

also is the main goal to level out the truck from front and rear measuring the fender to ground?
Here is some good information that might help answer some of your questions HowStuffWorks "Purpose of Towing Weight Distribution Systems"

The following talks about leveling of truck and trailer. Note that this article talks about wheel well measurement. It does not use measurements to the ground.

"There are two main elements to keep in mind during the installation process. The first is the change in the height of the wheel well rims of the two vehicles. You'll want to measure them before, during and after installation to make sure the weight distribution system is spreading the weight evenly and appropriately. The second aspect is the angle of the bars -- they should run parallel to the tongue of the trailer or downwards towards the ground, and often the head assembly can be tilted to accommodate this or the amount of chain links can be adjusted."

From your measurements regarding rear and front squatting it appears that your trailer is tongue heavy. If I were you I would borrow or buy a tongue scale and measure the tongue weight of the trailer fully loaded as you would tow it. During the tongue weight-in process then you can adjust the load inside the trailer to better balance the trailer.

This is the scale I bought and use. Sherline Trailer Tongue Weight Scales. The first time I used the scale to measure my tongue weight was an eye opening experience as to how much my tongue weight ACTUALLY was. The scale also let me easily balance the load in my trailer and took all the guessing out of the job.
