There are waste, grey water and fresh water replacement tanks that fit a 17'
Boler. Depending which side of the 49th you live. South of the 49th is a company called Pelland Enterprizes and north of the 49th is Edmonton RV Superstore.
For the Edmonton one you needto talk to one of the old guys as the young kids have no ideawhat you are looking for.
Pelland should have an online catalogue or just call them and ask for at ank catalogue to be sent to you (800) 216-2786
Let me know how this works out for you.
