^^^^^^^ My Son towed that exact same trailer with his 15 LB SRW no weight distribution for a couple years many times with the trailer weighing well over 14K.
IMHO it's not about can or cannot but rather a better towing setup.
We put a WDH on our 16' stock trailer that generally weighs in about 10-12K max and it made a noticeable difference in towing. It wasn't bad before it's just better now.
Other than a stiff ride when the trailer is empty I don't think you'll regret a WDH.
Rather than a link or two I suggest tilting the head back about 10 degrees. That will give you a bit more tension, plus the hitch won't bottom out if you go over a rise.
Be ashamed to have an issue and not be insured.........
I was only trying to balance the cost of a WD hitch against the "if" costs where something goes wrong. As for my acquaintance and other attorneys they all said basically the same thing...that if you don't follow manufacturer guidelines (which gets the manufacturer off the hook, leaving you) it will be an uphill argument at best and anyone suing will probably win. Don't know their success rates but in appearances they're doing well.
I didn't notice any swaying going on. Not a great test, but it seems to work ok.
