All thank you so much for the quick response I have come to the right place this is a very knowledgeable and active community!
Ok based on your responses I will probably switch my order to an HD setup then, let them do the install at my home, then add a SD receiver later. I will probably have to pay for the SD receiver out of pocket (less than $100) since I think the free receiver is only available on initial setup package. Not a big deal. I am going to start getting gouged at month 13 anyway when the teaser rate expires. I tried last night Directv will not let me a-la-carte order a HD dish, HD DVR, and plain SD receiver. I think they know I am up to something :) I tried to explain that I already have a SD dish on my "garage" and want to use the SD receiver there and not switch out the dish. I'll try again one more time when I call them back today.
