I've had my truck for about 1.5 years now.  The previous owner turned it into a "pimped out" luxury truck, with every toy known to man, and I thought I'd let people know how that worked out...

My truck is a 2000 F250 4-door 4x4 superduty v10 gasoline engine. It is black, with the silver lower half, with the standard-length bed, and cloth interior.

The additions: (things the previous owner added)
--------------

Shiny side-step bars: These are an essential necessity. The 4x4 truck sits up fairly high (with no extra lift - just the factory height), and without the side-step bars it would be a challenge to climb into. The side-step bars also come in handy for reaching the top of the truck to wash it.

Sun roof: This was not a factory option, but the previous owner had one added. They did a *very* good job, and it adds a lot of light to the interior.

Truxedo Bed Cover: This is a soft/roll-out bed cover. It has metal guides all along the sides, with velcro to vasten it down along the sides. At the end, it has a metal bracket that latches into place, and can't be opened unless the tailgate is open. The previous owner had a special electric/keyless lock added to the tailgate, and this works very well with this truck cover. This is just a theft "deterrent" - if someone really wanted in, all they'd have to do is cut the cover with a knife.

Lund Bed Extra: Not sure what this is called, but it is a fiberglass piece that makes the bed blend in with the cab (looking like the Chevy Avalanche). This helps improve the "lines" of the truck (otherwise it the 4-door cab looks awkardly stuck-on to the bed.

Clear tail lights: I wouldn't have changed out the original tail lights, because these clear ones aren't as visible, imho. But they do give the truck a nice look.

Air lift bags in the rear springs: You can increase or decrease the pressure in these via 2 little nozzles mounted just below the tailgate (a little hard to get to).  I guess these would be good for hauling heavy loads, but when the previous owner delivered this truck to me from NY to NC, he had 2 BMW motorcycles in the bed, and did not even add any extra air to these bags (left them at the minimum 5-lb pressure) and the factory suspension handled the weight of the 2 bikes just fine.

Trailer hitch & brakes: It's got a pretty serious hitch on the back, and a trailer brake controller has been added.  The brake controller is digital, and mounts with velcro on the dash, just to the right of the steering wheel. There's plenty of room for it, and it looks pretty good there.

Rubber mat in bed: Rather than a plastic or spray-on bed liner, it's got a rubber mat in the floor of the bed. This lets you see how your bed is doing, and things don't slide as much as on the plastic ones. I think I prefer this.

Stereo: The previous owner put in a very fancy pioneer stereo. The main unit is located under the center section of the front seat, and is pretty big. In the dash is the dvd screen, which also serves as the control screen for everything. You *have* to use the remote to control the volume, change stations, etc. (That's somewhat of a pain, the head-unit not having a volumn knob!) There's an old large XM unit under the passenger seat, and a cd changer under the rear seat (all integrated with the pioneer).  Behind the back seat are 2 amps (left and right), and also an self-amplified Bazooka tube. Extra 6x9 speakers have been added to the rear doors, in boxes that extend out from the door about 2 or 3 inches. For having so much stereo, it only sounds "ok".

GPS: Bolted to the left side of the front dash is a ball-mount which I can attach the bracket for my Garmin 2610 GPS. The power/speaker wire and the antenna wire are run behind the door trim. The antenna cable is snaked out to the roof and attached via it's magnet mount, and the speaker wire is snaked under the bottom door trim, and up the side-post between the front & rear doors, where there is a small speaker mounted (this is right-near the driver's ear, so the driver is the only one that has to hear the voice-directions from the GPS). The 12v power line is run directly to the fuse box, right under the steering wheel. This is a pretty good setup for the GPS, imho.

CB Radio: The cd radio is mounted in the hole where the ash try would be. It fits quite nicely there. It is wired to speakers behind the dash, and the antenna is mounted on the side-rail of the truck bed.

Scanner: There is a scanner is the driver's door, in the compartment under the arm rest. It can be plugged into power, and into the GPS speaker, via custom wiring.  I haven't used this much, but I guess certain people (volunteer firemen, etc) might like their scanners.

Windshiels Visor: At the top of the windshield is a "visor" thing. This sticks out a couple inches, and (I suppose?) keeps frost from dropping down and forming on the windshield(?) It's also got some spots for orange running-lights in the top of the visor. I guess the lights are a nice addition, but I don't know of any real advantage/purpose for this piece :)

Black Grill: The shiny chrome grill has been replaced with a black (painted plastic) one. There's also a black bug-deflector at the front edge of the hood. Therefore the entire front of the truck is totally black (including black bumper). Quite a mean-looking front-end.

Special Headlights: The headlights have been replaced with some special fixtures, and high-intensity (blueish) bulbs. Personally, I don't think I can see as well with these headlights. The fixtures have several bulb places in them, and some "fog lights" have been wired through some of them (with a switch inside, velcroed to the dash). I guess this is a cleaner installation than adding extra foglights (but I would think foglights would do better installed down low).

Wheels: The previous owner put some black wheels on (to complete the all-black look). But these were lug centered wheels, and he used the factory hub centered lug-nuts, and therefore the wheels had a very bad 'wobble' at certain speeds (because the wheel was basically "walking around" behind these factory lugs with the flat washers built-in). Just about the time I figured out the problem and put the right nuts on it, one of the wheels developed a stress-fracture, and developed an air leak through the middle of the metal. I got new wheels - this time shiny American Eagle's (and I used the right lugs! ... no problems so far with wobbles/bounces/etc like the old wheels with the wrong lugnuts!)

Rear Mirror: An aftermarket rear mirror was added, which has a digital compas, and thermometer. This is kinda nice, and tells you when the temperature crosses freezing. The mirror also auto-dims so lights don't blind you from behind.

Alarm/Remote: It's got a fancy aftermarket alarm system, which controls the remote door locks, and also provides remote start. I guess the remote start is kinda nice in extremely cold weather, if you want to warm the vehicle up some before you get in.

Side Mirrors: My truck didn't have the big towing mirrors, but instead the "small" mirrors. These small factory mirrors have *horrendous* blind spots with a truck this long (especially with vehicles on your right side, just about even with your bed). I bought some Pano-Mirror glass to put over the factory mirrors - this made a *huge* difference, and it is much safer to drive now (no blind spots at all).

Problems:

I recieved the truck with around 80k miles, and I have put about 6k miles on it. I have encountered very few problems, but I will list them below...

Tires bounced/wobbled at certain speeds (previous owner's fault - he used wrong nuts when he added aftermarket wheels).

Rear end leaking fluid - had the rear pinion seal replaced, but that didn't fix it. Turns out the fluid was leaking out between the splines in the rear end (the shop fixed it with some permatex sealer - no leaks since then).

Check-engine light: Read the code, and did some internet research, and found it could be a vacuum leak between certain components. Used a hollow tube, and listened for the leak, and sure-enough found it. This was a big-honkin vacuum tube (about twice as thick as my thumb), and special pre-bent angles and such. I went the ford parts place to get the exact right thing, but they had a devil of a time figuring out which part#. Turns out this piece failed a lot, Ford was making people buy the 2-piece unit to replace it (although only one piece was bad). U-Haul made them start selling as 2 separate pieces, and this had the guys at the parts-counter confused as to what
the part number was. But they worked real hard at it (even coming out and looking at my truck) and got me the right part.

Small Dent: There was a small dent behind the front tire (previous owner). I took this to a paintless dent removal place, and they pushed it out and it looks like new (that's the good thing about real metal :)

Power locks: The left rear power door lock "drags" and usually doesn't work with the remote. I took the door apart, but couldn't figure out anywher that was binding (maybe somebody jimmied the door, and bent something?) Anyway, this is kinda a pain.

Power window: The right front power window is pretty slow going up. I don't know if it's a "tired" motor, or if something is binding. Some wd-40 along the tracks helps somewhat for a little while.

Gas Mileage: This v10 will get about 15mpg on a long highway trip. But around town, in stop-n-go traffic, it only gets about 8mpg. (I guess that's about what you'd expect with this big engine, and motivating this big heavy truck through start/stop traffic).

Parking: With 4 doors, and standard bed, this is a very long truck. You will usually need to back it into the parking spots. You will not want to try to manuever in tight parking lots. I always park way out at the end.

-----------------

Overall Impression:

As a pimped-out luxury truck, these F250's have an impressive look & size, and can still haul all the redneck toys (ATVs in the bed, and pull trailers and boats). So, it's probably a decent choice for the good-old-boy that likes american trucks. There's a lot of room to add lots of "toys" and add-on stuff.

But, if you're not an real-truck die-hard, and don't need to haul stuff, you'll probably be happier with a more "luxurious" vehicle (maybe Cadillac Escalade, Lincoln Navigator, etc). And you'd probably want something with a little shorter wheelbase (these F250s are really long, and can be a bit awkward to park in tight parking lots).

March 2009 Update:

I replaced the 12.5" wide aftermarket tires & wheels with factory wheels and regular size (Michelin) tires.  They ride 100% better, and it's *much* easier to turn this truck in tight parking lots!

The motor in the right-side mirror wouldn't go in 1 direction, so I replaced it (with a used one I bought on craigslist).

Both last march, and this march, the engine was "missing" (like a bad spark plug), and had a pending engine code for a misfire.  The repair shop had to replace the "coil pack" for an individual plug each time.

Oh! - And I found out why the left/rear door lock was dragging.  The previous owner had drilled through one of the plastic knuckles for the lock linkage, when he installed the extra speakers. Doh!
