What size of solar panels are needed to keep battery charged for a few days of boondocking.

Do an energy use survey...actual or what you’d like to use. Your choice. That determines the battery amp hours needed, which determines the solar watts you need to recharge and the controller size. If you guess, you will be either undercharged or overpaying.
“battery charged for a few days of boondocking” is absolutely wrong. A properly sized solar system recharges fully almost every day. Limping along...for a few days? Solar isn’t a new toy or experimental.
Good advice.
I have a Kill-A-Watt meter that has been invaluable for getting real world power consumption of my 120v loads. I also have a Trimetric TM-2030 for measuring consumption of my 12 volt and 24 volt loads. The Trimetric will be my onboard battery monitor.
