I actually don't have a G27, though I do have a 22, 23, 24, and 35 in 40 caliber. I have won more than one IDPA match with my g26 and feel very safely armed with a "Baby Glock." I visit various forums on Glocks to see if there is anything new. I do my own action jobs etc (it's so easy).
I DO think you will run into problems with 3 large dogs. If they were under 40 pounds or so it would be simpler. Some locals and some apartment complexes are more tolerant. The weight limit on dogs at the last place I stayed was 50 or 60 pounds. They were pretty cool and would even tell you to your face that they would not weight the dogs or anything. But travelers with dogs are often forced to find their own housing. If you were to go to a small or medium sized city, the apartment selection will be limited as will the policies on large dogs. Larger cities will have a bigger selection of choices. Of course, travel companies often contract with certain apartment complexes for the short term leases of the travelers, so that may limit the selection there as well. The onus may fall on you very likely.
If you are a staff nurse right now, you may be surprised what they are paying travelers now, certainly more than when I was traveling 7 years ago. I have a freind, who is an OR nurse, traveling right now and he could buy and sell me with what he is making. CVICU nurses are always in high demand with bigger bonuses.
As far as other info goes, I would tell you this: Do not, and I repeat, do not feel loyal to a given company. I shopped them against one another. The smaller companies would often pay more but the bigger companies have cantracts with more hospitals. i would be talking to 2 or 3 of them at a time. Everything is negotiable. I negotiated bonuses that were not offered, had them add pictures on the walls etc. I learned this from more seasoned travelers while I was doing it. There are so many companies out there doing it also. There is a magazine just for travelers with lots of ads for companies (though the name is spacing me at the moment). Standard nursing mags have lot's of ads as well.
I think I read your in Fl, so you have one of the 2 toughest licenses to get with Cali being the other. I would get a license from a state like NC wich has reciprosity arrangemets with other states so you don't have to get a license for every state you work in, it gets expensive after a while.
I can tell you that you can do it your way and make good money. We had a traveler come through here that had been doing it for 20 years. He had 2 or 3 RV's (all airstreams LOL).
If you are in Fl I would keep my permanent residence there since they don't have a state income tax, even if your residence is a tent in a campground.
An accountent made quick and effecient work of the tax preparation, despite that fact I had 10-40's from multiple states and only cost me about $200. You'll really like the tax benefits: mileage, meals and expenses etc.
Back to the subject of vehicles: I would have to lean towards an RV, but heck, you'll find out when you get there. I cannot stress the importance of a vehicle with traction. You will be required to work the hours outlined on your contract (I assume you have not seen one yet), and they are very specific about this. I have been pressured to stay at the hospital or a nearby hotel during inclement weather. You won't be able to do this because you have to tend to your dogs. And if you rent you may find your self farther away from the hospital than you want. Of course you could focus on the sothern states that attract snow birds in the winter. The census is usually up in these regions in the winter anyhow.
Just be smart and organized and you'll be fine.
BTW, I have to agree with the suggestion of the Honda Element. I have a freind with one, they are very roomy. But they lack towing ability.
Anyway man, good luck in your travels and I hope this helped a little. I ended up stopping in one of the top rated cities to live in and settling down permanently as a result of me hitting the road. And do post back with your decision.
