I don't think the RB2 Pro-Series Round Bar WDH has any kind of built in anti-sway system. A WDH with integrated sway would be better, or maybe 2 anti sway friction bars may work. IMHO, a WDH with integrated sway control is better for that long of a trailer.
A loooong wheelbased truck would be beneficial also. I see where a Dodge 1500 is listed, but no mention of cab/bed configuration.
Also, the listed empty hitch weight compared to the total dry weight is minimal at best. 10% is considered the minimum, with 12 to 15% better for handling. That trailer will need to loaded front heavy as much as possible.
Once loaded for camping, 800 lb. bars may not be heavy enough.
