We ended up switching them to a cluster of femtocells scattered around the facility which operated through the broadband system we had installed. They are still using the femtocells now 8 years later, although they will probably switch to a WiFi-based system now that that is becoming more common (and that still goes through their broadband service). 

I know that Verizon is heads and shoulders above most other carriers, especially out west. There are huge areas of the country with not many people, and way too many mountains; both combine to make offering cell service a challenge. There are many places I've gone where Verizon is the only service available.

I would also suggest caution with cell repeaters/boosters. If you can not keep the indoor and outdoor antennas far enough apart, all you get is self-interference. It helps if you have a metal roof, but that is not an R-pod.

Even with an RPod, visibility can be limited. For our Nissan Frontier, I purchased a set of heated power towing mirrors  from 1A Auto. I looked and there are towing mirrors for the Tacoma as well in various configurations including some with turn signals and blind spot detection. They are not cheap, $159.95 and up depending on features, but the additional visibility is great since you can then see things behind the RPod better than with stock mirrors.

They make my little Frontier look all grown up.
