Welcome to the forum!
You are correct about not being able to OC anywhere that sells alcohol. Here is the law which lists the places in which you can not legally OC (without a CPL).
750.234d Possession of firearm on certain premises prohibited; applicability; violation as misdemeanor; penalty.
(1) Except as provided in subsection (2), a person shall not possess a firearm on the premises of any of the following:
(a) A depository financial institution or a subsidiary or affiliate of a depository financial institution.
(b) A church or other house of religious worship.
(c) A court.
(d) A theatre.
(e) A sports arena.
(f) A day care center.
(g) A hospital.
(h) An establishment licensed under the Michigan liquor control act, Act No. 8 of the Public Acts of the Extra Session of 1933, being sections 436.1 to 436.58 of the Michigan Compiled Laws.
(2) This section does not apply to any of the following:
(a) A person who owns, or is employed by or contracted by, an entity described in subsection (1) if the possession of that firearm is to provide security services for that entity.
(b) A peace officer.
(c) A person licensed by this state or another state to carry a concealed weapon.

Check out the carry chart in this thread:
Make sure that if your university has a no weapons policy that you don't carry on their property. Even though it's legal, you could get expelled.
As for transporting a pistol in a truck, you must have it in a locked case which is not accessible to you while driving. Put it as far away from you as possible. If you can transport it in the bed, that would be the safest way, legally speaking.
As for transporting it somewhere to OC, here is what the law says:
750.231a Exceptions to MCL 750.227(2); definitions.
(1) Subsection (2) of section 227 does not apply to any of the following:
(a) To a person holding a valid license to carry a pistol concealed upon his or her person issued by his or her state of residence except where the pistol is carried in nonconformance with a restriction appearing on the license.
(b) To the regular and ordinary transportation of pistols as merchandise by an authorized agent of a person licensed to manufacture firearms.
(c) To a person carrying an antique firearm as defined in subsection (2), completely unloaded in a closed case or container designed for the storage of firearms in the trunk of a vehicle.
(d) To a person while transporting a pistol for a lawful purpose that is licensed by the owner or occupant of the motor vehicle in compliance with section 2 of 1927 PA 372, MCL 28.422, and the pistol is unloaded in a closed case designed for the storage of firearms in the trunk of the vehicle.
(e) To a person while transporting a pistol for a lawful purpose that is licensed by the owner or occupant of the motor vehicle in compliance with section 2 of 1927 PA 372, MCL 28.422, and the pistol is unloaded in a closed case designed for the storage of firearms in a vehicle that does not have a trunk and is not readily accessible to the occupants of the vehicle.
(2) As used in this section:
(a) "Antique firearm" means either of the following:
(i) A firearm not designed or redesigned for using rimfire or conventional center fire ignition with fixed ammunition and manufactured in or before 1898, including a matchlock, flintlock, percussion cap, or similar type of ignition system or replica of such a firearm, whether actually manufactured before or after 1898.
(ii) A firearm using fixed ammunition manufactured in or before 1898, for which ammunition is no longer manufactured in the United States and is not readily available in the ordinary channels of commercial trade.
(b) "Lawful purpose" includes the following:
(i) While en route to or from a hunting or target shooting area.
(ii) While transporting a pistol en route to or from his or her home or place of business and place of repair.
(iii) While moving goods from 1 place of abode or business to another place of abode or business.
(iv) While transporting a licensed pistol en route to or from a law enforcement agency or for the purpose of having a law enforcement official take possession of the weapon.
(v) While en route to or from his or her abode or place of business and a gun show or places of purchase or sale.
(vi) While en route to or from his or her abode to a public shooting facility or public land where discharge of firearms is permitted by law, rule, regulation, or local ordinance.
(vii) While en route to or from his or her abode to a private property location where the pistol is to be used as is permitted by law, rule, regulation, or local ordinance.
The last statement of lawful purpose should be enough to cover transport with intent to OC. However, this has not been to court so it would be wise to not answer any questions asked of you by police as to how you transported your pistol.
Hopefully this information helps out. Don't hesitate to ask more questions! (After using the search function, anyway. :P )
