If you're moving around a lot and using for road trips, it may be a better idea to look into getting a weboost antenna for more consistent reception and just using your phone's hotspot.
Lived in rural Arkansas for a while and operated solely off of a Verizon Jetpack. Speeds weren't always consistent, especially with multiple people connected at once. I would recommend it as long as you don't need to upload large files.
I have a pair of the XKG pants and they've held up well. May not be my first choice for late season but they breath and stretch well and have held up to well hiking and range use.
Been going through the same process recently and I think I've landed on the exo. I like the seek outside packs but I think the simplicity of the exo is really appealing.
