Now, OP, you left out the most important part. You have a new trailer. You have a truck.
How did the trailer get home? Did you tow it? How did it tow?
That’s where you should be going first…. Not the salesman recommendations. If you got 5 bucks in your pocket, the butcher is still gonna recommend getting a filet, even if you only need to make a couple cheeseburgers. It’s his job to sell you chit whether you need it or not.
Dont be a sucker for salesmen.
And especially don’t be a sucker for hitch accessories. Half the time they’re like the “interior protection package” you get offered with a new car. Largely useless except for extracting money out of your wallet.
Now go take the trailer for a rip down the freeway and come back and tell us if it was scary, bumpy, swervy, or just fine.
Betting the latter….good luck!
