We are at the next phase of our traveling dream project. The water and holding tanks.
We were able to find New Old Stock for the freshwater tank and thankfully even with shipping the tank was under $300.
After several attempts to use the correct word or word combinations in the forum search and reading several great threads, I still can not find a direct replacement for the Main and Auxiliary tanks for our center bath '79 31ft Sovereign
. I have seen where some have done custom tanks but in order to keep on budget (okay to keep from going over budget by thousands and thousands and thousands of dollars since the budget was shot after the first project), I need to try and find tanks that are more common and hopefully carried by local venders.
I have sent off correspondences to places like Inca and InLand. But the tanks will run 350 or more plus shipping. I also asked Airstream directly if there are current replacement tanks or cross-referenced to other tanks. They told me to contact Inland, Vintage and Silver Trailer Supply. They do carry several different tanks but nothing with the same part number or are not close enough as replacements (as "off the shelf" replacements).
Google search and I can find several blogs and threads for rear bath sovereigns.
We are replacing most of the interior but would like to keep, at least close to, the same areas for the kitchen, bath and toilet.
Has anyone used "off the shelf" waste tank replacements for their center bath? What model number or numbers work the best?
