Definitely read the thread posted by BarneyS. First problem was having the dealer do the install. You should go back to square one and go through the installation and setup procedure yourself and understand how it all works. Use a torque wrench to check tightness of ball, hitch head and cam arm bracket forming screws.
What are the spring bar ratings? That 38' TT with a 10,500 lb GVWR will have a tongue weight of around 1200-1300 lbs and possibly a bit higher. I would go to a scale fully loaded for camping and get the actual tongue weight (and GVW & TV wts). If spring bars are undersized, you may not be able to get enough wt. back onto the steer axle. Reese has a chart for sizing the bars. Note that Reese is different from the other WDH manufacturers because they size bars by using tongue wt. plus TV cargo weight. See chart below. I *think* if you need the higher rated 1500 lb spring bars, it also requires a higher rated hitch head. I would not be surprised if bars are undersized.
The spring bars need to be set so that when chains are under tension with 5 or 6 links (trunnion bars), you get the correct amount of wt. back onto the steer axle. Bar angle needs to be set correctly to get the right no. of links under tension. Can take a while to get it adjusted where it needs to be. Yes, VERY important to get the bar "crooks" centered exactly on the cams and should be done with the TV & TT loaded for camping. Travelling with a full holding tank(s) can affect the adjustment too depending on tank location.
With that high tongue wt. I would use the heavy duty snap-up brackets and probably should have them also bolted to the A-frame with Reese's forming screws. Periodically check tightness of the cam arm bracket bolts because with high tongue wts. they can sometimes loosen a bit.
Once you have it all dialed in these WDHs are like wow! These WDHs do take more fiddling but def. worth it. A photo or two of your installation could help. Don't forget the other factors that can contribute to sway reduction like correct tire psi and having the TT level to slightly nose down.
