A 14ft. triple axle trailer!? That trailer would have more length in tires than not! I bet it looks funny.
Anyway, you'll be fine as long as the trailer has electric breaks. Many of us here tow more than that quite often with great results. I've got a 30ft Travel Trailer that's 10ft+ tall and 6,000lbs easy. I can overtake slower traffic with ease.
OD off for me.
