Do you think I could get away with using anti-freeze in my waste tanks and visit say Yosemite during winter (teens at night and above freezing during the day)?
I've been camping at ski resorts several times with my motorhomes and never did anything to holding tanks.
On motorhomes they just hang under the body with 0 protection.
From what I experienced the "dirt" in water lowers the freezing temperature, while RV with running heater keeps "warm air bubble" around, so in those nights with tens of F never had a problem.
Obviously staying in temperatures below 0 will be different story.
The 4-seasons campers I own dump furnace air into the tank compartment with no return ducting, meaning your warm air goes around the tanks into the woods.
Not my favorite design and I put a valve on the duct going there as I don't like my heat going outside for nothing.
Would I camp i really cold weather, I think some antifreeze would be my favorite. Don't think you need it in black tank at all, just grey water tank.
