I've been hauling snakes around with military moves for the last seven or eight cross-country moves. It's very challenging and there are some major roadblocks you may encounter that you'd have no control over. As you noted, you can't live in military housing...which can be a huge problem for someone new to the military, but not an insurmountable one for a married couple.

I only have five snakes. (And a bearded dragon for a few moves before we rehomed him.) I can imagine doing this with maybe two or three more snakes, but that would be my absolute limit. Sometimes, when you move, you can be several weeks between houses and the logistical issues involved in keeping/hiding these animals in hotel rooms or temporary housing can be both tricky and very risky. (I lost a $1000 snake during one move! )

You may also get sent overseas or to Hawaii, either of which would mean you absolutely can't take your animals with you. You have to have a plan in place for such a situation.

My advice...imagine yourself doing a cross country move, driving through the southwest deserts in the heat of the summer...with at least two weeks between permanent homes....and figure out ahead of time how many animals you can transport during this transition and how, exactly, you would go about doing so. Also, imagine all the worst-case scenarios with regards to getting sent overseas or forced to live in base housing or being unable to find a place to live that allows your animals.....and have a specific plan in place for dealing with those situations as well.

Good luck!!
