Ya the plug ins are right there behind your trailer
It depends on the site and of course the lenth/connection on your trailer, but I expect a 15 ft works most of the time. 25ft if you habe a big trailer to be safe. Oh yea don't count of WiFi, it sucks
It depends on the site but I would say to 10 ft coax and a connector in the middle
It all depends on how close you get to the power outlet and if your trailer is cable ready. But to be honest we didnt even hook ours up. Just did an analog search on the tv and that was good enough for us. Plus we didn't watch tv that much just use the radio!!
