Welcome Newbie! We just bought our first trailer last year, a Zinger 331BH. Our tow vehicle is a 2020 Ram 2500. Our first trip was last August, from central Wisconsin to Estes Park, CO. The trip could not have gone better, even towing through the Rocky Mountains.
You didn't say where you were traveling, or how far, but the biggest tip I can offer is carry an extra 5-10 gallons of gas in the bed of your truck. Twice during our trip we were unable to get to a station quickly enough and had to tap into our reserves. It was shocking how quickly our truck would go through gas, especially in the mountains.
Enjoy yourselves, and please post a trip report of your adventures, along with a list of the things you learned along the way.
