Tom, I can't say how long your daughter's account will be active, but Dish only charges us $5.00 or $10.00 mo. for the additional receiver. (Neither one is connected to a phone line.)
We have a receiver both in our MH and our house. It does make it convenient, but I would definitely put the one with the card in the MH. On two different occasions lately, when we didn't travel for a month or more, we couldn't access any channels in the MH. We got a message saying our Smart Card wasn't authorized to view the channel. We would then need to call Dish and they would do their "voodoo" which runs you nuts, and then our channels would come back. Once, when we were gone about five months, the same thing happened at our house when we returned.
We have a manual Sat. dish on top of our MH with one LNB, and if we are staying someplace for only a couple days, we use it and access one satellite (119). We also carry another Sat. dish with two LNBs, and a tripod that we set up for longer stays. After four years, we are seriously thinking of changing to Direct TV so we can access all the channels with one LNB.
Just for information... We subscribe to our local broadcast channels (NBC, CBS, etc.) here in Dallas. We found we could still pick them up about 235 miles from our home, although Dish said we could only pick them up 20 miles from ouor home. When we made a 400 mile trip to Corpus Christi we could not pick them up there.
