North Dallas/Addison

Short answer, NO. There are no parks anywhere near Addison. The nearest is a park along US 75 in Richardson. It is mostly a mobile home community that has seen better days. I seldom drive by that there isn't police activity in the area. Much further north, in Melissa, is the Lighthouse RV Park. It is an OK park, but a long drive to Addison. Other options are going to put you at Lake Lewisville or near Denton, an even farther commute. If it is a relatively short visit, park your rig and get a hotel room, you will be glad you avoided the traffic.
