Just don't forget to turn off the monitor when not towing. Ours automatically goes blank if it can't find the camera, forgot about it and it constantly looking for the camera drew down the truck battery so low we couldn't jump it with a pack, had to leave another vehicle hooked up for ~20 minutes to get it to start. I'm worried it toasted the battery as it's a PITA to replace, but it's been good for the last 3 months since this happened so I think I'm good, glad that lead acid is so forgiving!
A good way to ensure that would be to wire the monitor in to a circuit that's only active when the key is in run. On some vehicles, the lighter socket on the dash qualifies; on others, it's live all the time.
