Every RV'er needs this MDS. There is one for 30 amp or 50 amp. Make sure you get the correct amp for your rig. The Blue tooth and the wireless units work extremely well. The model I got is the "Hardwired" unit. If you don't know anything about electrical work, I recommend you get the pedestal model and buy a good lock for it.
