Are you sure your RV had a red and black wire...or was it a white and black wire?
Many RV's are wired kinda using a 120 volt wiring color scheme. If you have a white and black wire, then usually the black wire is the positive on the battery and the white is the negative.
If you do have the vehicle 12 volt wiring color scheme, then yes it's usually the red on the positive and the black on the negative.
You would think they would make it simple. The best way is to trace the wiring if you can and see.
However, if you have it hooked backwards it should be blowing the reverse polarity fuses almost instantly from when you put them in, as long as you are not utilizing a battery cutoff switch or something.
