Just bought a new Sunset Trail and finally got around to checking the USB plugs one on each side of the king bed and another one by the dinette, none of them work, anyone else have any trouble with those? I wonder if they are wired together and maybe a fuse is bad?
Don't know anything about your trailer, but USB outlets come in 2 flavors: powered by AC meaning you have be on shore power for them to work, or powered by your battery meaning they still work boondocking without AC power. I have both kinds in my trailer so I always have USB access.
Good news, we were camping last weekend and by habit I plugged my generic Fitbit into the USB outlets, it lit up so I plugged it old iPad into it and it worked, what I figured out was the new USB cords I bought on Amazon work on almost every outlet except those, got home and used the Apple iPhone cord and the outlets worked.
