There is a South East Lazy Daze Club that has a couple of outings per year, and like most LD clubs, they welcome wannabees. They just completed a outing, but will likely have another closer to the Fall. The North East group will be meeting in the Hartford CT area in a few weeks. Your welcome to attend, but it is a 2 day drive from Sarasota. The LD sites on line are restricted, but you can argue your case to join because of looking to purchase. There are rigs for sale from time to time, but as noted by another, they can go fast.
When looking at used, do check for leaks. Also check to make sure all appliances and the generator work. Request paperwork that documents required service on the truck. Check the tire date codes on the tires. The tires will need to be replaced if over 6 years old, no matter how good the tread looks. Determine the conditions of the coach batteries and the chassis battery. Try to find a LD with a fuel injected engine, rather than carb.
The mid-bath floor plan is the most common. A 27 foot LD mid-bath has an OCCC of about 2900 pounds, permitting you the ability to carry a fair amount of people and stuff. Some full-time or near full-time in their units.
Best wishes for success.
