Quite a juxtaposition!
1: Holding tanks- I have been using KO for years per Peggy's recommendation. I just tried "Happy Camper" which I bought on Amazon. This stuff is incredible. No smell! Cheap! Strongly recommended.

2: Mattress- Looking for recommendations. New mattress? Froli system? Topper?
Who make a good mattress?

For mattress, innerspring, memory foam or latex?
