I drive an 01 Silverado and here is my setup. For daily use locally I carry a Wouxon KF 805G, attached to a roof mounted antenna and powered by the battery eliminator. When I go in a store or whatever I disconnect the coax, slide off the eliminator, attach the "rubber duck" antenna and slide in the regular battery and off I go. For "road trips" I fashioned a mobile mount out of some plywood and "L" brackets for a mobile CB and mobile GMRS. While driving it sets on the Trans tunnel, If I'm staying in a hotel I disconnect both radios and carry the set up into the hotel room. The KG805G isn't high powered but it works for me locally. The mobile setup isn't pretty, but I'm not in a truck show. Hope this helps and enjoy!
