It's not so much how big or heavy your trailer is, it's what you will put in it. Remember that dry weight does not usually include propane, the battery, water, filled holding tanks, and all your junk. I think, though, that the Husky you linked may be too stiff for the trailer you are towing. That Husky is designed for a tongue weight of 800-1200 lbs and your tongue weight is only 440 lbs. This Husky might be more appropriate for your trailer:

You may also wish consider a WDH with sway control. I was checking out accidents caused by sway and was surprised to see that small trailers could sway cause comparatively large tow vehicles to roll. Presumably, a lot of this sway was probably caused by improper loading.
I tow a Trailmanor which has about the same dry weight, and I use a medium weight Reese WDH. It does make a difference. I was surprised that the first time we towed, even though we were under the GCWR we were over the GAWR for the rear axle. This was primarily because of the way we packed, but I was surprised how easy it was be overweight on the axle. People and stuff adds up!
