Agree with a little weight in the front of the trailer. Add a tool kit,
you may use it. Don't severely overload the trailer tongue, this takes
weight off your steering axle (bad idea).
Agree on using trailer tires, they take more pressure!
Also:
Check tow vehicle shocks, change to heavy duty.
Check tow vehicle front end alignment.
Check tow vehicle and trailer tire pressure.
Fiberglass top trailers may need spoilers added to the vertical fin.
