Black/Water Holding Tanks

Good Morning! We have just purchased a 1978 17 ft Boler. We are in the process of removing the interior. We will need to replace the holding tanks (black and water) as they are leaking. Can anyone tell me where to find tanks that will fit. Thanks.

Do a search on this site, it has been brought up many times for fresh water tanks, most places that make fresh water tanks also make black water tanks.
I found a company in Ontario that had a black tank that fit my Trillium with a web search for "RV holding tanks"

Hi Don. When you say your tanks leak, are they cracked or is it an area around a fitting? Because most fiberglass trailers use Marine Toilets... the black tank is actually inside the trailer right under the toilet bowl. Is yours like that or a completely separate tank? What you need to do is measure the physical dimensions of your tanks. Here's a link to tanks from the Helpful-Links: Let us know how it works out. Knowledge is power!
