Haven't got any experience, but on the new RV show sponsored by Lazy Days, a couple had their MH updated with some new cabinets etc at the shop there. I think it is filmed in FL, but there is a Lazy Days in Tuscon, maybe they could help.
Either way, I would ask for references and call the people. See if they have any samples of their work that you can actually see the type drawers, or upholstery trim, etc. I know I would want to actually see something they had done.
