Maximum Distance with a CB Radio

What model CB radio will fit in my 4×4 and give me the most range?

I have a 2000 Honda CR-V 4-wheel drive and the CB radio that’s in it at the moment doesn’t do too well. I want more grunt with my next radio.

I am looking to get maximum range while transmitting & receiving, and I would like the most power at the best price (on a tight budget here)…

What is the best recommended antenna/radio unit for this type of application?

I can hear police radio communications with my FRS radio
