E350 with Dual Cam

Hi all, was setting up my new 2011 E350 with my dual cam setup from my suburban. 26' keystone loaded 6500lbs This is what I have

Unloaded front height D 35 7/8 P 35 7/16
Loaded front height D 36 1/8 P 35 13/16
Loaded w wdh D 35 15/16 P 35 11/16
Loaded Difference D 1/4 P 3/8
After wdh return to front D 1/16 P 1/4

I measured the frame rail in the front (21") back (21 3/4"). Driving it seemed a little squirly. when cars passed me I got a push pull and even running around corners there was a push pull. The most noticeable was when I let off the gas there was a noticeable push pull of the camper.

I am wondering do I need to tilt the head down just the next notch? I am wondering if there is not enough pressure on the load bars. Do you think that I am a little light on the tounge weight? I checked the cam on the bar and they seemed to line up. Honestly, solid wise it doesn't feel too much different than the suburban. All tires are aired up. Tounge weight with suburban was 690-780 but if I remember correctly it was also 2" front to back pitch nose down.

Any Ideas?
  • Did you run through the cam-lobe centering procedure?

    Your numbers look good, although a little extra tension (by tilting the head) would probably be better. But the cams must be centered or they fight each other , and it will feel squirrelly. Once they lobes are centered in the cams if should feel rock solid. Also don't grease the cams.

    When I had my Weekend Warrior, I would have to re-center the lobes if I had a dramatic change in loading (i.e. no toys vs 4 snow machines in the back).

    It will function with any amount of tension on the bar. Obviously it will provide more control with more weight.

    My question is, how often is a Toy Hauler towed without toys in the garage? If it`s like me (I don`t have a TH) I have the same load for every trip. I can`t imagine owning a TH and not having say a motorcycle with me every trip! I could be wrong, but it seems to me that`s why you buy a TH. not being a smart... here just asking because I don`t own one.

  • Anytime you change the number of links to the cams, you should readjust the cams to be centered in the bar crook. You probably could try just changing the bar load, and take a quick test drive. But, best is to readjust, then test. You may have to do a couple of times to find the right combo.
  • Try going for a drive with the WD bars a bit looser, you will have plenty of weight capacity on the rear axle, and no worries about overloading it.

    The extra weight on the rear axle will be good for stability.
