I purchased a 2003 DP last year in "good" condition for a very good price.
Upgrades and required maintenance parts:
Flat Screen TVs - $360
4 Aluminum wheels and 2 new Yokohama tires - $ 2,270 (tires were 8 years old, stored inside and only 4,000 miles)
2 Relay boards for slideouts - $250
Batwing TV antenna - $130
Portable Satellite dish - $450
Radiator surge tank - $225 (installed)
Miscellaneous replacement items - $300
New inverter - $1,200
New batteries & cables - $ 800
That's a little over $6,000 and does not include the complete fluid change, filters, air dryer, nylon sway bar bushings, serpentine belt, etc.
Just completed a 4,700 mile trip and worth every penny of the upgrades.
