Hello Kevin - I know your post was from awhile ago but I thought I'd add my two cents in case others are still reading.
We only use our wifi data for entertainment -not a job. I set up our system based on Verizon. On the west coast it is definitely the most reliable. I purchased a Weboost cell signal booster [attached to the old tv antenna on the roof so we can easily raise it from inside], WiFi Ranger Spruce, Verizon MiFi Jet pack and a phone from Visible Wireless. Visible has unlimited data for a flat $40/mo and works on the Verizon network but can only be hotspot connected to one device. So, I have connected the phone via hotspot to the router and now we can have all our devices running off it inside & outside the coach. We only use it as a dedicated hotspot not a phone. One additional thing about Visible, because they work off of Verizon towers it's a lower priority than actual Verizon customers; so there are times when the Visible phone is slower. But that is when we switch to our MiFi or our phone hotspot. I wish I wouldn't have purchased the MiFi. We get plenty of hotspot high speed data off our two phone that are on an unlimited plan from Verizon and our Visible phone. I hope this might help someone trying to figure out how they want to set up their data.
