Additional information:

Trombetta builds a similar model, the 114-1211-010, that has copper contacts. This model is NOT designed for connecting batteries for charging. MurCal does not sell it. 

RV manufacturers typically want to keep their costs low, however, Winnebago chose not to upgrade to the 114-1211-020 and asked Trombetta to modify the housing:

They drilled 4 holes in the top of the housing to let moisture out of the housing.  The 4 holes also allows moisture into the housing too. 

We recommend stating silver alloy contacts, they are more robust than copper contacts and they will last longer.

Refer to page #2 in the Sales Bulletin in the Coils/Contact table showing 25K cycles for copper & 50K cycles for silver alloy. 

Silver alloy contacts are the best choice for your RV.
