We would like to know how long we should expect the average batteries (we have two new ones) should last when wilderness camping; only using the water pump to flush the toilet and the minimum light at night with our 5th wheel?
Our second question is, in what states is it illegal to have your LP gas on for the refrigerator when traveling down the road?
ANSWER: Hi, how long your batteries will last while boondocking (camping in the wilderness) depends on the type of batteries that are being used as the house batteries on your 5th Wheel Trailer.
If the house batteries are standard 12-volt car batteries, they will last the least amount of time. If the batteries are 12 volt RV/Marine Deep Cycle batteries, they will last longer than the car batteries. If the batteries are 6-volt true deep cycle batteries, they will last the longest.
If this all sounds confusing to you, take a moment to read the answers I gave to the questions below and then return to this page to get the rest of your questions answered.
There are also portable solar charging kits available such as those offered by Zamp Solar. In the video below RVing Expert Mark Polk from RV Education 101 shows you how easy the Zamp Solar Portable Battery Chargers are to set up and use.
As far as your question on driving down the road with your refrigerator being powered by propane. To the best of my knowledge there are no state laws in the US prohibiting using propane in an RV while going down the road.
Some tunnels in the US do not allow you to go through the tunnel with the propane on; they have signs letting you know to turn off your propane before entering the tunnels. Most of them provide a pull-out so you can shut off your propane. Ferry services also require you to turn off the propane when your RV is being transported on them.
Hopefully, the above information has been helpful to you.
