You're overweight a little with the trailer, but not desperately so.
There are some roads where it just can't be helped. The DOT in their infinite wisdom decided to build concrete roads with expansion joints that are at the exact right distance apart to set up a harmonic porpoising in your vehicle at a particular speed.
My DRW, empty or loaded, bucks like a wild bronco on the last 5 miles of I-490 East, and it's a nightmare between exits 39 and 40 on the NYS Thruway (I-90). Seems like the slower you go the worse it gets.
