For us preparing to be trailready in our K5s what is needed CBwise? I've heard of unlocked ones with extra channels and stuff, antennas, etc but not sure where to start
Just a basic, 40ch CB. No need to get fancy with it because you will generally be talking less than a mile with other rigs. I've seen marginal setups talk 10 or more miles with a clear line of sight. My little $40 cb had done fine the times I've had it on the trail and the one before it did good, it just had the weather channels and some sound processing for the extra $30 it cost.
Even with the extra channels and all that, you'll still have to know what channel someone is listening on and since standard radios are more common, you're most likely to get someone in an emergency on the designated ch9.
