Thanks to Peggie and others. I am following closely on all the advise since I am probably soon to follow on the unpleasant work. I have first to determine if the holding tank on my ‘95 40.5 has been replaced or is original. Looking down on what i can see under the nav station seat I can see some white material but nothing clearly aluminum. How do I make the assessment? Secondly, what are the initial steps to access? Thanks, Eric
