There is a very large custom Bus style Rv dealership in Sanford, Disney has busses, there is lynx busses in Orlando, Votran busses in Volusia county, anothere buss yard in Ocoee, several large RV dealerships in Orlando, Hientzelmans Ford is a commercial based truck dealership several large dirt construction companies, I don't think you would have trouble finding a job between Seminole, Orange and Volusia counties. Thats just what I know in this 3 county area. And with all the campgrounds and snowbirds if ya had the equipment you could probably do VERY well as a mobile RV mechanic on your own. I personally like the Volusia and Lake county areas along the St. Johns river for access to freshwater within minutes and a short drive to several saltwater locations and would have you within 1.5 hours of Melbourne. Really would suggest ya think about renting for a bit to get a feel for areas ya might like. I also know a realtor that would take really good care of you. Best I know in the area, would gladly PM you the info if you are serious about buying in this area, she will get it done for ya. Best of luck to ya, keep us updated and look forward to maybe seeing ya fishing.
