In looking at the numbers above I am seeing that I need to be on the 5th link correct?


My torsion bars are rated at 1000lbs. So my first step I guess is to upgrade to ones with a higher rating. I neglected to measure the front and rear trailer heights so I will do that after I get new bars so I can work on the hitch set up.
The weights for your rear axle can't be right...they're more than the total truck. Do you have a front/rear axle weight of the truck alone?

By your measurements, it looks like the 5 link set-up is the way to go. I am surprised that the front height came down that much with the bars loaded. Perhaps using 1200 or 1400 lb bars may change that...they would stiffen the ride which would be beneficial.

The rear axle numbers are WITH the trailer attached.

Dave your right. Sorry, I neglected to do the math the rear weight is that number minus the front axle.

So it would be...

5280

And

5380

By those numbers the weight added to the truck is 1460 - 1480 lbs which would account for tongue weight, weight of the hitch/bars and anything else you may have added with people/cargo from the weighing of 7140 lbs. It's also interesting to note that although you moved 80 lbs more to the front axle by changing 1 link, you didn't transfer more weight to the camper's axles as the total truck weight remained (relatively) the same.

So I was ambled to negotiate with the dealer to upgrade my hitch to a 1400lb set up. Will pick up tomorrow and see what kind of difference that makes.

Not sure how I missed it but there is a similar current thread describing almost the same thing(Roo propoising). Sorry for the repeat thread but thanks for all the help!

Ok so I got a 1400lb set of bars/hitch and I immediately noticed a stiffer drive with a lot more control. After some measuring this is what I got...

1400lb bar measurements

Unloaded

Hitch 19 1/2"
Front 21 1/2"
Rear 22"

Loaded no bars
Hitch 16 1/2"(not sure why I got a half inch difference here, maybe bad measurement the first time?)
Front axle 22"
Rear axle 20"

2 links
Hitch 18 1/2"
Front 21 1/4"
Rear 20 3/4"

3 links
Hitch 19 1/4"
Front 21 1/8"
Rear 21"


Didn't notice a huge difference driving with either 2 or 3 links.

Here is the new bars/hitch, the jack is off the wood about 1/4 inch or so. I did move the saddles up a a little but ran out of room.

All you're usually trying to achieve with the W/D hitch is to maintain the normal ride height at the front axle of the TV. Your set up with 3 link more than achieves that and could perhaps reduced by one link. I think I'd leave it at 3 links, tow with that and re-evaluate if needed.

What I don't see in your posted pictures of your set-up is any sway bar(s). That camper is 36' long and you should at minimum, have 2 friction sway bars. The better set-up would have been a W/D hitch with integrated sway control such as Equal-i-zer or Reese dual cam.

He's got mounts for friction sway on the passenger side. I'd definitely add a second one, though.

It's laying on the ground just out of the shot. I have a single passenger side set up.
