    Hi Mark. Question for you on charging my 5th wheel RV batteries. My unit uses a 50 amp connection. At my house I had an electrician wire up a 50 amp connection so when the unit is at home, I can connect it and charge the batteries and have full function of all electrical without having to run the generator. At the storage lot where I keep it however there is no connection other than a standard 110/120 AC outlet that I can connect to. My question is this: Is there an adapter or some method I can connect from this 110 outlet to my 50 amp connection for the sole purpose to keep a trickle charge running through the onboard inverter.& charger just to keep my batteries charged up ??? Or is this something I would not want to do ??? I use the camper at least 1 every 2 months, and ever 3 weeks or so that I do not use it, I do go and crank up the generator and let it run for a while, and/or bring it home and connect to shore power, both of which obviously charge the batteries. You can respond to me at BobLZX12@cox.net, and I would greatly appreciate it !!!
