Grant, The Aladdin Tank module failed on my Patriot not long after we bought it in 2015. The shop was able to find a used but good module and all works fine now. An RV salvage yard maybe your best bet (Colaws, Verunkins, maybe others.) On our travel trailer, I installed a SeaLevel system, easy and it works great. You can get these with a remote (or two) display so you can see your tank levels at the wet bay and at a convenient place in the coach. And, if money is no object, the whole Aladdin system can be replaced with the Silverleaf system (Albany Or.) for $5-7K. Food for thought.
