Lazy Days in Tampa, FL should be a great dealership because of the large selection. I would also recommend you do several online searches for some price comparisons. I highly recommend 3 to 8 year old coaches from quality manufacturers for full-time RVing. This way you get the best bang for the buck. Also, get a coach you are likely to enjoy living in for several years, or you will be the one losing a ton of money when you trade it in to make an upgrade.
I have written a few helpful articles for anyone that is contemplating the full-time lifestyle:
RV Lifestyle Articles.
Now is the time to do a ton of reading and research so you can learn from others trials and tribulations. I wish you much success in your search for the perfect RV for your full-time RVing adventures.
Happy New Year!
