We had a travel trailer and used one of our sd home receivers and a "shaky" tripod with a round dish for our d tv while camping. It was pretty easy to get locked on a good signal, except when we were in Maine where the sats were kinda low on the horizon. Now we have a fifth wheel and will be spending considerable time in it. It has a 40" tv. We'd like to get an hd/dvr to get the same service we get at home. Doesn't matter if we hook up the bedroom tv to the sat. How much more difficult is it to set the slimline dish up for hd vs the round dish for sd? On the slimline 5 lnb swm, would this enable us to bring in only one coax to the rv sat connection or would we have to install a new thru wall connection near the sat box? Directv can send us a sd/dvr for free and $5/month for the extra box or $100 up front and $5/month for the extra box. Don't mind too much spending the extra one time $100 for the hd/dvr if the setting up isn't too time consuming after going thru the learning curve. I've looked at "satellite tv for rv.com" and their package combo for the slimline looks ok. Would still have to purchase a slimline swm dish/lnb. Anything else needed for setup? Like a meter other than the one included in the tripod combo?
