Jeep ? Off Road ? What kind of antenna will you be using ? Limited space ? CB only ? AM/SSB or just AM ? Loud and Clear ? I really don't see any need for these high dollar radios for a situation like yours but that really depends on your space and needs ? A good strong, dependable,limited size radio that would tune up very nicely for you would be a Cobra 25 ,Uniden 66,68 AM only type radios , they also can nicely be tuned for upwards to 45 to 50 watts Pep ...(if you wanted to go that route?) ....even just with a basic tune up they will hold there own with or without a power mic , I think that would depend on who did the tuning and what kind of antenna you might be using. Whatever your choice may be ? Good luck to you all the same. (-: SK
