I have some thoughts around upgrading my 2015 17' SD. The purpose of the upgrade would be to be a little more boondock ready and allow for some comforts as well.
My rig is pretty standard but I added a charge controller and external plug so I can plug in my 150 watt portable solar panel that I keep stored in the camper shell of the truck and pull out and plug in when I need to.
I want to augment that with some more battery capacity. I am thinking of removing the existing battery and putting 2 new AGM batteries with a battery box under the bed which is permanently configured that way. I am thinking around 300 AH of capacity. I would want to minimize the amount of floor space required so that I can still store stuff under the bed and keep it to the rear left corner under the bed so that it doesn't interfere with the access panel on the right where the water pump and water heater is.
After I do that, I would put a 1500 to 2000 watt inverter in the spot where the old battery was. Since these things generate a lot of heat, keeping it out of the rig but still protected from the elements seems like a good idea.
The inverter would be used for the coffee pot, microwave, toaster, nuwave induction, TV, etc. as needed.
To complete the set up I am thinking of a good battery monitor so that I can know exactly the state of charge and AH in and out.
A remote for the inverter so I just hit a button to turn it on and off seems useful.
Finally a manual switch that allows the inverter power to go to all the existing 110 plugs in the rig or use the shore power, as needed.
I am trying to slowly add what I would need/use and see how it goes. For example, I could see adding a generator for topping up batteries later on.
Does this approach sound reasonable? Any suggestions are welcome.
