Check your tongue weight. Sounds like it is swaying.

Hi,
I bought a boat and trailer with total weight of 5,000 lbs. The trailer
is
dual axle with brakes on all wheels. The trailer brakes by the tongue
moving into the trailer. My tow vehicle is a 2001 1/2 ton Suburban with
5.3
L engine.

All does great from 0-50 mph. It struggles the closer I get to 60+.
There
is a slight sensation of push/pull from the trailer. I am concerned that
perhaps the trailer's brakes are to sensitive or that I am out of
horsepower
from the Suburban. I pulled over after 50 miles and the hubs felt cool.

What do you think?
thanks
