Thanks a lot for all the information.
So now, I'm thinking of putting the controller next to the breaker box, it seems like there would be back and forth going from the controller to the battery and back to the breaker, but I think it's okay because I don't want to put the batteries inside or move them elsewhere. Then I wonder
1. Can I plug the shore power to one of the inverter's outlets using a 30A to 15A adapter and have all the outlets inside the RV working or would that cause any problems ?
2. Also the roof of the RV is metal, I'm not sure how I would go about screwing the panels ? Some people say they used 3M double sided tapes, but that doesn't seem like it would hold very well. What's the best way of holding these panels with minimal damage to the roof ?
I'll be using very little of the cement actually, I have the layout where the "living room" is in the back, and the floor between the kitchen and the bathroom has like less than a quarter of inch edge, I'll be using the patch only for that part. I even considered just leaving it as is (as in don't add vinyl flooring), but it doesn't look too good, also I'm not sure if it's going to cause damage it in the long term.
Also, I was considering flat mounting a 25" monitor on the roof of the cabover part of the RV, it looks like it's fiberglass, I wonder if it would cause damage to the roof in the long term ? The monitor itself is 15 pounds.
And does anybody have a trick for getting to the roof of the RV when there's no ladder ?
Thanks.
