Towing T1661

Hi,
I have a T1661 that I tow with my 1999 1/2 ton Suburban. Ii have only towed on the ball. Most trips are fairly short with limited highway travel. It seems to tow fine. We are now planning longer highway trips. I am wondering if I should add load bars and/or sway control. If so, what should I get? I am looking to get a larger trailer, maybe 24'.

Should also add that the TT tounge has what looks like factory anchors for weight distribution and sway attachment

Thanks,
Jim
