Cross-Country Road Trip in a '68 Barracuda
I would not tow a small trailer which will drop your legal speed limit to 55 mph in most states.
Your front end alignment is important. I had my '72 BBody checked before I left and even replaced a few front end parts. However, when I arrived at my destination (about 1,500 miles later) I was shocked to find the steel belts showing on the almost new front tires. A loose ball joint had thrown off the toe-in (although the vehicle tracked just fine down the highway). Keep an eye on the front tires at every fuel stop please.
