winter travel

jack buck, we do a bit of winter travel (sometimes below zero F) with our fiver, water tank full and water system full,so... keeping heat on is a must. But most of our trips are short so battery consumption is not an issue. On a very long trip (as stated) a generator to maintain batteries may be needed. Or.... and I “ have not” researched this (though I did this on an old ‘84 Ford to charge our 5th wheel batteries), rewire to your truck 7 pin connector with a separate lead from truck battery ( the original lead is “only” to maintain your unit batteries and is of low amperage). But..... you must unplug when truck “not” running, so as “not” to pull down your truck batteries!
