Got a newish used RV sewage tank last week for the darkroom trailer last week. New cost was $249, used with delivery was only $100. Before I was using a 15-gallon tank, this 25-gallon version fits and works much better. Slowly and surely am making improvements to the working systems and tools. Climbing the mountain to making 35x35 plates 100% in the field across Canada.
Note* This last week the tank worked great, but I almost ruptured myself trying to get it out of the trailer to empty. I need some kind of pump-hose system which will allow me to remove the wastewater without too much strain. I found out after words that 25 gallons of water weighs an astonishing 200lbs!!
