Neat set up. When you can, post a pic of the trailer and truck together. I'm sure it will look outstanding.
We tow a lot with a vintage TV, as do many of our friends, and it is fun. We used to only use the wagon but now from time to time we just find it easier to hook up the truck, for those ugly trips where you wouldn't want to take the car, but for the most part we enjoy taking the wagon when ever we can.
As for travel taking longer, we came to the conclusion years ago that it isn't a race to get somewhere, if the distance means a fast dash then we just go somewhere closer rather than hurt ourselves, the trailer, the TV, or someone else. We enjoy the side roads and two lanes and when towing with vintage you will find that people along those roads really seem to appreciate seeing you come along and pass by.
Enjoy your new ride
