The radio used in the 199ML is the "Jensen AWM970" and I guess you found that, the refrigerator looks to be the same model as mine, a "Dometic DM/RM2652 Americana", although some models are equiped with the "Norcold" type, the range is a cooktop type "Atwood/Wedgewood Vision", same as mine except I have the full oven instead of the cooktop, as far as the slide goes, all the Passports use the cable operated BAL system but the Express looks like it uses a non cable operated type, probably a Lippert slide system (I think I have the manual for that in the slide-out folder), also with regard to the refrigerator, you'll get two blue plastic funny looking objects, these are for inserting in the door catches and holding the refrigerator doors ajar for air circulation while not in use so mold doesn't form inside. I don't know how informed you are about all the systems on the unit but if you have any questions or need any manuals feel free to ask.
