Tackett,
The way the law is written, if you do not have your Concealed Pistol/Revolver license you cannot carry a loaded firearm of any kind in a motor vehicle. Car, truck, motorcycle, ATV, etc. including attachments, which I believe would include trailers or possibly even camper shells.
The natural resource code reads:
(9)
Have in his or her possession a crossbow with a nocked bolt,
a loaded firearm or a firearm from the magazine of which all shells and cartridges have not been removed, in or on any vehicle or conveyance,
or its attachments, within the state, except as may otherwise be provided by law or regulation. Except as hereinafter provided, between five o'clock postmeridian of one day and seven o'clock antemeridian, eastern standard time of the day following, any unloaded firearm or crossbow, being lawfully carried in accordance with the foregoing provisions, may be so carried only when in a case or taken apart and securely wrapped. During the period from July 1 to September 30, inclusive, of each year, the foregoing requirements relative to carrying certain unloaded firearms are permissible only from eight-thirty o'clock postmeridian to five o'clock antemeridian, eastern standard time: Provided, That the time periods for carrying unloaded and uncased firearms are extended for one hour after the postmeridian times and one hour before the antemeridian times established above if a hunter is preparing to or in the process of transporting or transferring the firearms to or from a hunting site, campsite, home or other place of abode;

with an exception made for concealed carry permit holders under WV Code Chapter 20-2-6a here:

§20-2-6a. Carrying a concealed handgun.
(a) Notwithstanding any provision of this code to the contrary,
a person licensed to carry a concealed weapon pursuant to the provisions of section four, article seven, chapter sixty-one of this code who is not prohibited at the time from possessing a firearm pursuant to the provisions of section seven, article seven, chapter sixty-one of this code or by any applicable federal law
may carry a handgun in a concealed manner for self defense purposes while afield hunting, hiking, camping
or in or on a motor vehicle.
I'm not a lawyer, and this isn't legal advice. Its a laypersons interpretation of the text of the law. It is worth precisely what you paid for it.
