You have to be careful approaching turns with that much weight. The TT probably weighs more than your truck. (your profile isn't complete and doesn't say what you're towing with) When you go into a corner and let off of the gas and then turn the wheel, the weight of the trailer is going straight forward, the truck starts to turn, the trailer wants to continue straight since the truck is not pulling it at this point, and then the trailer causes a jack knife.
You see that a lot up here with new people pulling four place enclosed trailers with light truck, no weight in them and all season tires after the first big snowfall. They head into some corner, usually too fast anyways, and the trailer pushes them right off the corner, usually rolling both units because the truck went off the corner broadside.
With that trailer, if it's snowy at all, always stop headed down hill because you won't get it started again without your chains on. And take a good hydraulic jack, not the factory jack for the chains.
