I recently noticed that one side (curb side) of my landing gear was extending more than then other while lifting the trailer. The Atwood landing legs are driven from the street side with a cross shaft providing drive to the curb side jack. Upon inspection all the machine pins or shear pins were intact and functioning correctly on both sets of bevel gears and the cross shaft. What I have discoved is two different gear ratios in the landing gear. The curb side leg has a 15 tooth side gear with a 15 tooth screw gear. The street side (powered side) has a 12 tooth side gear and a 16 tooth screw gear. Both of these gear sets are powered by a common shaft with no gear reduction to one side. Is this a factory error or am I missing something?

this is only an opinion but it sure doesn't sound right to me. makes leveling your trailer a bit tricky.

Jack,
It certainly doesn't make any sense to me, either.

Hillside jacks???  I'd almost bet a Dutchmen dealer would replace one side if you pushed the issue.

Now for the rest of the story; I contacted Atwood and discovered that the one jack (12/16 ratio) is the heavy duty model and the other jack (15/15 ratio) is the standard model. Somehow the trailer manufacture switched the two when assembling the trailer.  My first thought was to just change the gears in the one jack (15/15). The Atwood folks told me that would not cure the problem because the jack screw in the standard model is different that the heavy duty model. I ended up ordering a new jack assembly for the non-power side which will have the 12/16 ration and correct thread on the jack screw. I must say that the service center at Atwood has been outstanding in assisting me with this problem.

I went ahead and paid for the jack.  The trailer is well out of warranty. Kind of a catch 22 thing. The manufacture said they could not make such a mistake and Atwood said they just furnish jacks to the manufacture.

Did the manufacturer speculate an opinion on how the incorrect jack ended up in there? I suppose it was your fault!

A previous owner could have replaced the leg, if purchased used. After I bent our powered leg, I purchased two aftermarket powered legs. I can now adjust either side from one control box.
