Full time in my travel trailer, Challenge No. 1: Internet

Reliable Internet is one of my highest priorities since I work full time and require internet. I have two plans, one Verizon and one ATT both dedicated to data. Cell phones are ATT. I use a router that will load balance and fail over between each carrier if one goes to lunch. Been doing this for a year and a half w/ few issues. Park WIFI has been basically useless everywhere we've been. Satellite Internet has too high of latency and will not work for my needs.
