My experience is a drive of 150 miles or more should top off a battery that was partially discharged from a couple nites camping.
Correct. Purchasing a relay won't necessarily help out though. If the TV isn't wired up for a relay in the circuit you can buy as many as you like and it won't make a difference.
The OP needs to check his TV owners manual and find if there is a slot on the power distribution panel for said relay and then confirm that it is properly wired to the socket that the trailer plug into. Most OEM sockets that came from the factory should be all ready to go with nothing more than plugging the relay into the power distribution center.
