Salesmen around the world are famous for telling you that your truck will handle the largest trailer no problem. "You won't even know it is back there."
Actually you will be accutely aware of it.
Your truck is rated for around 6,000 pounds. Your trailer weighs more than that empty. You either need a lighter trailer or a heavier truck.
If you are going to tow in the mountains and turkey trails it is best not to max out your truck, and much better to stay several thousand pounds under the weight your truck is rated for.
