Thanks for the advice everyone!
A lot of the same concerns I have. About safety, my truck locks, heavy duty, someone would need to be prying my doors off or breaking my windows (which are shatter proof) to get in. Also, I am in the truck most of the time, and when I'm not, I would be taking my feathered child with me!
The temperature control in the truck is amazingly accurate (its a new truck), so keeping the temp in the truck is no problem. I can even add a humidifier. I would need to child proof some things but it can be done. Also again why I would not be taking a brand new member along with me
There is enough room to have a nice size cage for them, and plenty of room when I let them out. As stated, I'm not sure about how I could buckle them down however, while they are out and about the cab.
And as for vets, it would be a task to organize it, but since my driving routs would/should be fairly regular, I should be able to contact some avian vets in cities/towns along my routes that I can always stop at along the way when need be.
It seems to me that the big concern is just whether or not my buddy will want to travel with me or not! It will take some planning and prepping, but I believe I can make it work.
This is also why I am looking into Rescue/Adoption. Perhaps there is a nice old out there Grey who likes road trips
