Weigh your setup at a truck scale. It costs fifteen bucks. The peace of mind is priceless. Also, check tire pressure on both car and trailer before every trip. Underinflated tires explode. That’s bad.
Have fun, though. Seriously. Towing a trailer is like having a mobile shed of possibilities. You can haul furniture, take a tiny house on vacation, or cosplay as a trucker. Just do it smart.
One more thing: if you pass me on the highway and your trailer is swaying? I’ll judge you. So don’t sway. Be the chill trailer person. You got this.
