Would stainless be a better choice than a 105 gallon polyethylene plastic tank for long term durability?My friend works in a large machine shop that primarily does large stainless fabrication. They do a lot of food grade stuff. My friend just got me a battery tray made of 10 ga stainless. (Probably overkill, but not complaining.)Brian Elfert
My situation was I have a large combined waste tank (200 gal.) and a 140 fresh tank. The senders I used drop down from inside the coach so I put a small access plug that I can get to if I ever need to change or replace them. One of the problems I had with my old sender for the waste tank was junk (use your imagination) on the sender. The salesman and Wema suggested using a gauge that starts a ½ tank which works really great. The heavy ends are at the bottom and do not hang up on the sender. I have been using it for 3 years now without problems. The fresh tank works great and is very accurate.
