RE: Cleaning awning
Jomax house cleaner, and bleach. Mix according to directions. The Jomax is around $20 a gallon, but it is concentrated and makes 20 gallons of solution. I just washed mine today, and it is the best thing I have found.
RE: TN camping
+1 on very friendly owners, and a very clean park. There is a pool, but I do not remember a playground for the kids. It was 2 years ago in November when we went.
RE: Interor Lighting - LED Bulbs
I have the lights that zztinker talked about. They work great. You can figure 7 lumens per light so the 36 light module (7x36)= 252 lumens. That compares very well to the 264 lumens of the #921 incandescent bulb. I think it is plenty bright enough, but the same seller also has a 48 led module.
