In case anyone is looking I think I found a solution.
It's called MOFI. Add another line to your cellular plan, get a SIM card for it and pop into this.
Probably cheaper than HughsNet or FairPoint and no latency issues.
Works with AT&T, Verizon, T-Mobile.
You probably want a plan that doesn't throttle.
We were paying like $65 for FairPoint for fairly slow speeds over on NewFound lake.
I have not tested this myself but reviews confirm it seems to work for most people. Seems popular with RV owners.
