You are good on weights. The problem is that you have a long trailer and a short wheelbase tow vehicle. You definitely need very good sway control with your hitch properly set up.
In your shoes I would give it a try on secondary roads without a lot of grade, in good weather, and see how it does. Keeping your speed down will be a big help.
Biggest issue will not be pulling it, but stopping it. Make sure your trailer brakes are working correctly and your controller is dialed in.
Crosswinds could be a problem, too.
