Finally Starting To Plan A Garage(need some wisdom)

[Blue85]

Starting to plan my garage, crappy part is in town i can't build anything bigger than 645sq ft, so basically that means 25x25 or 24x26 etc. what do you guys think would be the best route? I'd like to be able to store one truck on 1 side and park my regular truck in the other in the winter. Should i use one wide door, or go with 2 10fts, think i'll build 12ft cielings just in case i have a higher lifted truck someday, the biggest hurdle is that i have to hire someone to do the footings, and pour the slab etc. Don't really know much about that end of it, but the framing i'll do myself. I plan to have my garage built and heated by October this year, seems like a while but i am on a budget. Thanks in advance for your input!
