If folks are like me and do not have that 50A or 30A receptacle to plug into when your Barth is sitting in the yard, Battery Tender has a solution that I have just installed and it works great. Mind you, my coach sits in the yard with everything off when not in use. This idea is just for those who are like me and park your coach between trips. When parked between summer outings, I feel that the only thing I need to do is keep the batteries in the coach at a full charge. Yea, I could use the kill switch in the coach to save the batteries from draining (though they will on their own over a period of time anyway), but that is unnecessary. Battery Tender makes a two bank charger. I mounted the charger in my compartment with the coach batteries. I purchased a 12' extension cable from Battery Tender and ran it over to the compartment with the chassis batteries. Now all I have to do while it is sitting in the yard is run a standard outdoor extension cord to the Battery Tender charger and plug it in. I can also do this while I'm sitting at the campground. From that point on all my batteries are kept up to charge and I do not have to mess with anything else. And yes, it will keep both of your paralleled batteries charged. All this convenience for under $100!

Bruce...That would work well im my situation also. What model did you get? Where? .. Thanks Gerald

E-Bay....my favorite shopping place. Do a search for Deltran part #220165. Different deals to be had. There is a deal on there right now that you can buy the charger with (2) 25' lead extensions for $97.95 (free shipping). Or the deal I got was the charger for $82.40 (free shipping) and then I bought the 12' lead extension from someone else for 12.70 with shipping. So the "package deal" is well worth it, though you will end up with 25' extensions...
