Have the same issue on a '97 Gulfstream. Was going to replace all the cabinet doors with pine (helps to have a table saw, router, etc.) and stain, but we decided to brighten up the interior and paint the cabinet doors and frames white. It's a bit labor intensive, but ended up scraping off the loose veneer (doors are a wood product called MDF) with a wood chisel, sanding the exposed MDF and veneer that was still well attached to a smooth finish (100 grit sand paper). Used a white primer designed to adhere to plastic surfaces and wood, then painted over with a semi-gloss. So far happy with the results, but it is a bit of work.
