We are heading that way this fall. Sounds like fun. Grizzly, you live around there? Looking for places to camp... .
As Bill Carlyle said, Red River, NM is alway a nice resort, which is very high in altitude (8500 to 9000 ft) and very scenic. Red River is located in the Enchanted Circle along with Angle Fire, Eagle Nest, Taos and Questa. These towns are circled around
Wheeler Peak, the highest point in New Mexico. All of the above towns mentioned have good camping and fishing. Taos, NM, along with Santa Fe, are one of the states largest attractions.
Don't forget the annual Balloon Fiesta in October in Albuquerque. If you plan to attend you should make RV reservations now.
Just some 50 miles north of Southfork, CO is Creede, Colorado, a great place to visit during Miner Competition Days, which is on the forth of July.
Wolf Creek Pass is another must see and must camp areas in Colorado near Southfork.
Let me know if I can tell you more, george
