Do I need a sway bar?

I have the Startcraft 14R/T OFF-ROAD POPUP trailer and it pulls just fine with my F150 Truck. My truck has the built-in sway control however. The trailer specs says 4200lbs. Your Trailmanor probably is rated higer than that... I never did weight it but it is always loaded down pretty good...

OOPS I just now looked at your link... Disregard my post....
