We just returned from a 3,000 mile trip to Washington state from San Diego.
Everything worked great except the heater acted up the morning after we ran through a pretty intense rain storm. Whatever got wet seemed to have dried out and the next day the heater was working fine.
We used the Winegard WiFi extender in each RV park except the last one where their WiFi was unstable, going in and out. Worked great. A little slow to get set up. I'm going to try getting its hotspot going. We have a deal with Verizon that gives us a SIM card for $5 a month. 15 gigs of data/month. Should suffice.
Now I gotta clean it!
