I'd pass on that. (personal preferance)
Not much range.
(a little more than line of sight maybe 3/4 to 1 mile very effective).
conventional CB's reach 5-7 mile (many get much more.. and then some get more than that.. but they would be illegal)
Hand Held Radio would prevent installation headaches and you would certainly be able to connect with fellow jeepers on a trail ride
it'll take a beating flippin around inside a bumpy old jeep. The antennae is fragile and long so you would have to ensure that it comes with.. or buy a 6" flexible rubber one.. more of "less range".
easy to store, portable.. stick to midland or motorola for quality and tuffness as well as audio that you can actually understand. Get the 12v car adapter because of extreme low battery life. Be sure the radio is at least 4watt output. (minimum should be a deal breaker)
Walkie Talkies are versatile and should not be discounted. the police use them.
some are very nice.. and with the long antennae you will have increased range maybe 3 miles.
you'll get what you pay for here.
pros: no installation, portability, use it anywhere, hide-ability (u can lock it up)
cons: range, bulky and heavy to hold, bulky to use, battery life, it can be easily misplaced, left behind, damaged or bounced outta the jeep.
Cobra makes a very small radio.. virtually everything is contained in the microphone. avoid it.
