Welcome to the group Bill
You are in a tough area to buy as, while there are a fair number of FGRV's in FL, there are a lot buyers ready to pounce on most of them.
But tell us a bit more:
What will you be towing with? Some FGRV's are deceptively heavy, and the 17.5', 2500 series
BigFoot is the most deceptive of all.
What is your acceptable age and condition. There is a full range FGRV''s out there, from 2015's that are like new, to 1973's that are like new, to fixers of all ages.
Can you travel outside of FL to Look/Buy, what is your range.
And what is your approximate budget. Like
weight, FGRV's can be deceptively $$$.
Good Luck hunting
