I would avoid Rugged and probably wouldn't go with PCI. They are used more in the desert/dune race areas and are programmed with business band frequencies that require a license.
True Rugged is licensed and they will tell you that you are good under their license but I bet they won't tell you that most of the frequencies they are licensed for are for certain desert race areas only. Rugged does offer GMRS radios as well but like their other radios they are $$$$ for what they are.
Rugged has also recently received another notice from the FCC.
For overland/back country adventures CB, GMRS, and ham are more commonly used.
CB is still popular among groups/clubs but it is the least performing of the options.
GMRS is increasing in popularity, Jeep Jamboree has mandated GMRS effective 2021.
CB and GMRS are fine for group/convoy comms.
Ham is far more capable, while it works just as well for group/convoy comms it's great for reaching out, there are far more frequencies to use, can be used for more than just voice...all sorts of things.
It really comes down to if you are running with a group...what do they run and are they willing to updating to something better?
