Ensure proper weight distribution:
Ensure you don’t go beyond the max capacity for the Passport which includes the trailer and what you’re hauling (3,500 - 5,000 lbs max I believe).
Leave more time for braking, it will take longer.
Don’t go too fast, especially at first. Get comfortable hauling it at like 60mph first on the interstate, and adjust from there.
Make sure you use the safety chains, crossing them under the trailer tongue and latching onto your hitch loops.
Leave a little room for the wiring so it has some give when you’re turning, so it doesn’t get stretched and snap or pull off.
Check your load whenever you stop.
Use ratchet straps, and not just the cam buckles which work loose (and this from someone who loves cam buckle straps. Ratchets are just superior even though more annoying to use).
Get good backing up the trailer before you go in a parking lot or something, but also try to avoid pulling into places where you’ll have to back up. Makes it much easier.
You’ll do great, good luck!
