Which portable dish?

I'm thinking about getting a portable/mobile dish with Wally receiver to use with our travel trailer. Looks like they all are designed to use western arc satellites, with a single exception - the Winegard Pathway X2. But it's (understandably) bigger and heavier.

So, do those of you who RV with a dish system ever find that WA-only is a problem and wish you also had EA capability?
