I have seen rented RV's at FW, so I know it can be done. They are usually Class C Motorhomes. I have seen CruiseAmerica ones, and others. I did a Google search for RV rental Orlando and got several sites.
You can try Cruise America. They have a 1 800 number and have stores all over. You can also go to a site called rvamerica.com it is a site run by Trailer Life and Motor Home Life. I work in sales for an RV dealership and while we don't rent a lot of dealers do. You can also check with the Orlando BBB and find out if there is a local dealer. But rvamerica.com might be the easiest.
