I'm interested in build a carport as practice for building two
porches. The home owner states that the carport is to be about 22'
wide and 26' long. Big enough for a Toyota Rav4 and a Chevy Express
2500 van.

I understand putting posts in the ground to support the structure
at the corners. Because of the lengths of the respective sides, do
I also needs posts in the middle of each side to support 2"x8"
lumber? That would make eight posts in all of 4"x4" pressure treated
lumber. If I do add a post in the middle of each side, how do I
join (or do I) the joists at the center post?

I plan to make a simple gable with 1"x4" purloins for corrugated
roofing. All the lumber where possible should be pressure treated.

There will be no electricity or other grid services in this carport.
Just a place to put a car out of the weather.

Other than my massive inexperience with this, what else should I
consider and research?

In most places, any permanent structure requires a building permit.

In many places, local colleges provide classes in house-building
methods (both masonry and wood.)
