of course, we got these at the dollar store, much cheaper.
We had a 2012 Shasta revere which didn't have enclosed underbelley or heated tanks.
We used 2 damp traps last winter and both were at least 3/4 full of water in the spring.
This winter, we used 2 new damp traps in the Eagle HT and I tossed them out today. One was nealy empty (i could tell it's done it's job though, the crystals were saturated but no liquid at the bottom and the other one had maybe 1/2 inch of water at the bottom. What a difference the glacier package makes!
