Your decals are in excellent condition for 21 years. Nice find! That tells me it has been stored out of exposure to sunlight. Your roof should be like new as well.
The headlights are translucent and yellow'd, the front bumper is badly faded, so I think there has been significant exposure to the sun. Yet even so, no worries. Everything can be addressed by a determined owner, without breaking their bank or back.
Ford Econoline restoration and repair parts are readily available and relatively inexpensive. I would bet far less painless than getting parts for the Newmar Dutch Star too. My replacement bumper cover came from Ford, but the new headlights came from Taiwan via Advance Auto Parts.
Reproduction decals are available,
but not from Phoenix. There’s several threads here on that topic.
If the microwave bezel is cracking (shoutout to Ron D for that thread) you can only repair and refurbish it, because Carol found me the last one!
The 2003 V10 was the last year with a mechanical throttle body and cable instead of an electronic throttle body. Before you get stuck somewhere with the mystery no upshift problem, I strongly suggest proactively inspecting or replacing the short molded vacuum hose on the idle air control valve , located next to the throttle position sensor at the back of the engine When you remove the dog house engine cover it will be directly in front of you.
