I use a 14,000/1400 pound capacity Eq on my 34 footer and have been very happy with it.
On the noise....I don't worry about it. You don't move the bars enough on the road to hear it. Only at low speed and tight turns will you notice that you sound like a machine shop coming through the campground
It's a good hitch though. The ball cant angle is one of the variables that you use to set it up. You do want the ball to lean back, toward the trailer. Changing one washer's worth of cant kind of gets you between two notches on the L brackets. So if one hole on the L bracket is too low, and the next raises you too high, go back to the low and change a washer on the cant angle. It took me a couple hours to set mine up, but once a person did it, you could probably set one up in 45 minutes pretty handily.
I agree with the others on the WD bars....you don't want them very heavy on this little camper.
Best of luck!
