Plans for a large carport?

This group has some analytical builders - so I address this challenge. With ten cars and trucks baking in the desert like sun - they lose more value every month. Wondering if anybody is happy with the carport design they implemented.
So far I am favoring treated 4x4s in concrete footers for main structural support and resisting high winds. 2 x 4 frame gets the job done. Maybe a rear roof slope starting at 6' (for cars) and going up to ~ 8' for taller trucks. Front roof would be 8' to 10' from side to side. Roof will be galvalume steel - have some used material.
Guessing the county would want a permit pulled. Kind of nuts all things considered but they can make ones life sheer misery. I am extremely remote from county services and city slicker eyeballs.

I'm going to build the carport. I have a lot of logs and time right now. This is not fast but it is good one: https://www.amazon.com/gp/product/B06XHLVY6Y/ref=ox_sc_act_title_2?smid=A1UMBRA5ZTBCX8&psc=1
Should do the job for a couple dozen ~ 5x5 posts. Lumber has gone up - a lot. Time to do it myself. I have pretty good chainsaws being a tool junkie.
