I don't have Dish in the RV or in the home, but I have been researching what it would take to convert a Winegard SWM3 Trav'ler to Dish AND be able to use a Hopper 3.
From what I can determine so far, it doesn't appear to be that difficult but it will take a few "pieces and parts" to do it, especially if your looking to use a Hopper 3 setup in your RV like I am.
There also seems to be an issue with leaving a Hopper 3 connected to the dish while the dish is acquiring the sats.
Here are a couple of resources I have been referring to. This one has some info and various wiring diagrams for the conversion and different setups with Dish equipment.

Then to get the converted Trav'ler to work with a Hopper 3, it appears I would need to do a bit more to make it work with a Hopper 3 setup. The above setup refers to a "hybrid" LNB but I have seen other posts mentioning that the better way is to install a hybrid "switch" and solo node like the video below shows.
There is probably more out there but I just started digging a day or so ago.
