A couple of recent purchases: Battery watering system & 50-15 amp ad June 14, 2008, 01:14:09 am Yahoo Message Number: 1220Just installed the Pro-fill battery watering system for the two Costco6V golf cart batteries in our Jayco Greyhawk. What a cool product!Battery access on the Greyhawk is pretty decent with the slideouttray, but this makes it much easier to maintain the batteries.Also, happened to pickup a Marinco 50amp to 15 amp adapter. Basicallyallows me to run the fridge and the lights when we have the MH parkedin front of the house while we pack for a trip. While plugged in thisway, do you know if the house batteries will be charging? I imagineit would.
