You should get a 1000.2 dish unless you are on the East Coast, then a 1000.4. Get a good tripod with adjustable length legs like the HD Tripod from
TV4RV.com. Adjustable legs make it easier to get a level vertical mast on uneven campsite ground. You might want to consider the whole package. A good meter makes life a lot easier, especially one that generates a 22KHz tone to select the 119 LNBF for aiming.
Given the typical wiring in an 5th-Wheel, there is a coax from the Antenna Amplifier plate in the living room to the bedroom TV. Flip that over to feed the Joey. If you want to be able to switch to OTA (until the OTA tuner for Hopper becomes available), use a good quality coax switch between the Solo and the antenna plate to that bedroom cable.
I would get another Solo and leave it installed in the trailer. Less set up that way. Just a cable to the Hopper and a cable to the Joey.
You Hopper timers will work until you leave the spot beam area. Then the Locals will not work, but the rest of your channels will.
Here is a link to my web pages on
Satellite TV, which includes my Hopper installation, drawings, photos.
