Most 10 meter radio's are between 25-100 watts, while legal CB is only 4 watts. Under FCC rules you can only use part 95 certified radio's only on CB (meaning, most Ham radio's aren't certified to operate at the 11 meter CB freqs).
The most common 10 meter rigs you'll see converted to use CB are going to be the 10 meter radio's, all band radio's occasionally, but those rigs are way to expensive to be playing on the CB bands (Usually the starting price for a 2 meter to 160 meter rig is around $500.00).
I have a number of different rigs, Cobra 148, Uniden Grant, President 2510, RCI 2950, Magnum 257 etc. I use the Magnum in my Bronco because of it's size and features are perfect for that application, that along with a Messenger 1200 amp, that way if I get into trouble, I'll be able to be heard to get help.
I'll agree on the licensing, but it's not to hard to get a tech license and start using 2 meter though.
