Another option is south of Tyler, TX in Bullard, TX. The name of the park is Bushman's RV Park.

The people who own this park also own Kiepersol Vineyards, Winery & Distillery. It is located very close to the RV park.
If you stayed there you would be looking at 1 hour to get to Canton. But after a long day of shopping maybe some wine or spirits may be in order. My DW has a tee shirt that says "Will trade husband for wine".
