i wouldnt and will not recommend a 2970 for that vehicle.bacause the vibration
jumping and shaking would shake something loose for sure its a heavy radio.
id recommend a cobra 29 black chrome with external amp.
galaxy makes a radio called the 29 might be ok
last choice would be the general lee many truckers use this
cb with great results and plenty of bouncing and shaking..lol
these are usually pretty durable radios.far as the beeeep sounds to me
like a squeal how close are you guys.if side by side drive away from
each other say 1 mile or so.if still there try another mic.could be
a bad wire in mic or on connector.last try aniother cb .this is the order
id try its cheapest first then moves to more expensive.also
get a cheap swr meter and check swr on ch.1 and ch .40
