I have personal experience with
www.alliancecoach.com in Wildwood, Fl., and
www.creativecoach.com in Lakeland, Fl. Alliance has their own campground,( no sewer, but have a dump), which makes it convenient because the workers will pick up your coach in the morning and bring it back for you each day. Creative has places to plug in but no campground. They both have paint booth's to handle big rigs, and do interior remodeling. They can do pretty much anything your imagination can think of, or you can afford. I would recommend them equally. But they each can be busy, so it's good to call ahead to make an appointment. If it's just chairs you're looking for, or maybe recliners, why not just go to a furniture store?
