We are fortunate to live a few miles from a Blue Beacon Truck Wash. I always washed our Class C myself, but decided to try Blue Beacon to save time. I had them wash it and then use the RainX protectant. The Motorhome came a lot cleaner than I could have gotten it and the RainX protectant made cleaning it the next few times myself a lot easier.
The supervisor walked me around the Motorhome asking if there was anything to be careful washing. I told him to be careful around the fridge vent, hot water heater and the furnace exhaust. After they washed it (6 guys with pressure washers), the supervisor walked me around it again to check their work.
That is the only Blue Beacon I have used (Brunswick, GA, just off I-95 exit 29), but I would not hesitate to use them again. Our current 40' TT with 4 slides takes me half a day to clean, so Blue Beacon would be a welcome alternative if there was one near our seasonal site.
