I would like to go into the States this summer, but, if this Covid #@%$! will be over we will be on our way!! When we do go I will have to find dealer and installer to do the install for me.
Another question I have is why doesn't Monaco have the 2003 Monaco Diplomat on their web site?? I live in Edmonton area in Canada. I hope I done this right as first time posting.
Your model also should be along with the year. I installed BigBattery LiFePo batteries in my 2004 Diplomate DST. The battery bays can be different.
I would suggest that you really look at how much you will be off-grid before you dump thousands into the batteries. Don't get the cheapest ones. My BigBattery has temp sensors and will prevent harmful charge and discharge at temps. I got 17Kwhr of batteries, but that ran $6k a year ago. Then, you may want to consider a new inverter, if yours is old and not able to program for lithium charging. Get a true sign wave like Magnum.
Then you also need to decide if you are going 24v or 12v. 12v is an easier swap, but can add thicker cables and double amperage if adding solar. If you are adding solar, this all goes together. Getting enough panels to charge the batteries per your usage. I added 2400W of solar to my roof, which then needed charge controllers....list goes on.
Just don't let a salesperson talk you into getting a lot more than you want or need.
