Gadget Guy,
Good summary of your experience. Here are some comments on my recent experience.
I decided to switch from Bell to Shaw for two reasons: hope that it would continue to work in the south, and the new rig came with a Travler Dish installed at the factory (a $2800 option). I was using Bell both at home and on the road and decided to switch both over to Shaw. This happened this year so the home system came with the 600 series receivers programmed for the new sat and, of course the dish had the current LNB. That was the easy part.
The Travler came set up for the old system. To bring it up-to-date, it needed the new LNB (that my home installer provided at no cost). The messy problem was that the Travler also needed new software and that required paying Winegard $70 plus shipping both ways for them to send me a box to plug into the controller to do the update. Two or three minutes and about $160 later I was good to go. (I suggested that in future Winegard might want to move into this century and offer downloadable updates and a USB port on the controller). This was a stupid waste of time and money IMHO!
Now, possibly the really tricky part, at least for new Shaw users that are not grandfathered on the old "Home Away From Home" program. Shaw apparently now only offers a second account with a 25% discount if you have a second location, be it a cottage, RV or winter home. So, in my case, the sweetheart deal might be that I pay 175% of my monthly subscription for service I may or may not be able to use while away in the winter. I don't think so! I only use the service in one location at a time and don't believe I should have to pay for it twice!
To potentially avoid this situation, my installer was adamant that all my dishes and receivers must be on the same program (I had suggested that he give me one receiver on the "old" system for the RV to avoid dicking around with the Travler since the new Sat wasn't going to be available down south anyway). His point was that if you are running two different configurations on your account Shaw might logically deduce that you are running two locations and charge you accordingly.
So, assuming the above is true, i'd be cautious about using two different configs on the same account.
FWIW
