Washing the travel Trailer

Wash the roof before the first trip of the year and after the last. Do my roof inspection for sealant that needs repaired. After washing the roof the awning gets scrubbed and then the four sides while the awning is drying. I use a wash and wax liquid mixed with water made by camco and sold at camping world. Next day i put a coat of liquid car wax on it, let it dry and buff it clean by hand. Two day affair, twice a year and she looks as good as the day I bought her. Occasionally I'll wash the front camp if I'm done a lot of night time driving and have bugs to clean off but generally, that's not an issue as I usually travel during the day.
