Congrats on your new North Trail and welcome to the forum and family. We owned the NT21FBS which was our 1st Heartland product. Had great luck with all of our HL rigs while moving up 1 foot at a time. Make sure you check out the HOC which is the best part of owning a Heartland rig. You'll meet great people with tons of knowledge who share your passion and by attending the rallies, you'll be able to put faces to the great people you meet here.
You'll find this forum to be filled with great info and tips, mods, and repair information. Again, look into joining the Heartland Owners Club, congrats on your new rig and hope to meet you down the road.
