I removed my leaking waste tank yesterday. Cut a hole in aft compartment to access and remove. Not too bad a job. On the way in I noticed that the fuel tank hoses need replacing just cracking with age. For general knowledge this is the size of the tank: 21” X 14” X 9” = approximately 11 gallons. I am debating whether to go back with a portable system or replace the tank. I know the portable tanks are less of a problem to deal with. With a portable toilet I don’t have to worry about a pump out station or lugging my transport tank down to the club to empty the tank myself. And then if I buy a portable toilet what is the best one to buy. I noticed some have capability to attach to a permanent tank on board, any thoughts on this any recommendations? Jim
