Wintering help for a 14 blue ridge 3710.

[cliffordredfx4]

So I was lucky enough to acquire a 2014 forest river blue ridge 3710. It is much larger than my rockwood roo 233s! I’m not familiar with a lot of the water system in this camper along with the black and grey tank differences. Unfortunately this camper did not come with any manuals and the former owner isn’t available to give me a rundown. Anyone have one of these campers that might be able to help me out?

Regardless of the size the systems are basically the same when it comes to winterizing. empty the black, gray and potable water tanks pump RV antifreeze thru all the water lines including the toilet spray hose if you have it the outside shower and low point drains, I also pour antifreeze in the sinks to fill the traps and get antifreeze up against the dump valves.
