We also just bougth a 2015 34 RL with an 18 cu. ft fridge. When you indicate that there is a need for 4 x 6 volt batteries are you talking about the 18 cu ft fridge or the 20 cu ft side by side fridge?

If its an all electric fridge, you will want the four 6 volt batteries and at least a 1000 watt inverter. The 20 cu ft 3-door Kitchenaid fridge draws around 1000 watts for a few seconds and then drops off to about 90 watts while running. If your fridge is all electric it's power consumption isn't going to be much different from one model to the next. My truck can can supply about 240 watts and the batteries stay well charged while on the road. Once you stop or dry camp, you are on the trailer's battery pack and you would like as much battery capacity as you can fit into your trailer. Basically you don't want to have to keep treating your rig like you would a parking meter and worrying about it. My math indicates that using four 225 amp hour batteries, I have about 60 hours of run time for my fridge on battery. That's accounting for inverter efficiency and the fridge running 45 minutes out of each hour.

I almost forgot; cut that figure in 1/2 because you do not want to draw your battery's full capacity. Drawing a deep cycle battery below 50% of capacity will shorten the life of the battery pack by as much as a factory of 5. That is, you need replacements in 2 years instead of 10.

Thank you William. I must admit I am a bit lost in this thus the reason why I am seeking information on the forum. I will review with the dealer as the unit is currently being ordered.

The inverter was 1000 watt and the performance on our first trip was not very satisfying as we had to reset it from overload about every other stop along the road. I have since upgraded the battery wires to a heavier gage and it hasn't misfired.
Sterlingsilver, Which heavier gauge wire did you upgrade to and did you also upgrade the inverter? I've had a similar overload reset issue in the past.
