Welcome to the JOF. I separated from service 50 years ago. Rented a room in a house near school. Didn't have a dog at that time though.
Be sure your floor plan includes enough space for your dog, which you will probably want to leave in a crate, when you are away from the trailer. My dog is #100 black Lab and requires a large crate.
A slide out adds a lot of floor space to a trailer. Also given where you live be sure to get an insulation package and a 15K air conditioner.
Good luck with your civilian life!
