KokomoCat,
I would suspect that you only have one satellite receiver feeding your two sets currently. You also probably have a Winegard switcher that runs 12v to your standard antenna as well as switching your antenna and satellite rf (eg channel 3) signals to your back TV. That setup does not work with HD. You need to have a separate satellite receiver in the bedroom for HD in the bedroom.
UNLESS he doesn't care if the same channel is on in both locations.
For a two room RV installation, I would not be surprised to see the bill for the dish antenna and installation to run at least $2000 itself (since there is some definite rewiring that has to occur for the bedroom TV. Plus, you need access to the back of the bedroom TV to connect the receiver. You would probably shave about $300 off this cost if you just keep SD in the bedroom, and drive it with a rf converter from the front satellite receiver (similar to the setup you have now).
The receivers only (no DVR) are $100 each plus programming and extra room fees. Recorders are about $200. Then there is programming. I am assuming you have DirecTV now since you are on this forum. You would just have to upgrade to HD ($10/mo) plus DVR charge(s) if you get the recorder.
You need a separate estimate on what it would cost to get the TV's installed. Costs there vary wildly depending on the modifications you want to make to your coach.
As an aside, I don't know what I want for our coach yet so I just bought a SWM Slimline dish (to mimic what we have at home) and an inexpensive meter to aim it with. Total out of pocket was about $300. It takes a few minutes to setup, but for now I am happy with the outfit. I just take one of the house DVRs and put it in the RV when we are on the road. I would really like to put a 32 inch HDTV in our rig, but that would probably take about $4000 to $5000 worth of cabinet work to make happen. I just am not ready to put out that kind of money for the conversion.

I do the same as you Bob, I have a Slimline I set up with a tripod and 50 ft of dual coax (HD DVR). Takes about 15-20 minutes to get TV up and running when were where were going to be .... When just traveling, we'll just use the OTA antenna for the time being till we get to our destination.
There was a box that runs it to the back bedroom already in the unit, Ran new coax to the compartment for the recvrs and mounted a wall mount for the TV to the old location that had a old style TV and strap it in when were on the road.
