Re: powerstroke diesel question: 7.3L or 6.0L
I did a lot of research on the 6.0 before I bought mine. Just make sure that you know what you are getting into before you buy and get an Oasis on it. There are some really good deals out there but you have to do your research to make sure you know what you are getting.
The problem years for the 6.0 were 2003 - early 2005. Most of the early horror stories were due to techs throwing parts at the symptoms. Everything looked like blown head gaskets when that wasn't actually the root of the problem. The biggest problem in the 6.0 is casting sand left in the block. Since the oil cooler and EGR cooler are inline, it clogs up the coolant passages in the oil cooler then starves the EGR cooler of coolant. This is ~$5,000 repair at the dealer, ~$2,000 in parts IIRC. I haven't heard of anyone having this problem after installing a coolant filter and changing the filters regularly.
If you plan to put a tuner on a 6.0, plan on putting in ARP headstuds...the kit is ~$500 but installation is a PITA. The book calls for cab removal, but there are how-tos on doing them without it.
The only downside to the 7.3 that I know of is the transmission. I had 3 of them (95, 99, and 01) and replaced transmissions like clockwork...but I towed with them and expected it. The transmission behind the 6.0 is better suited for towing and is much more reliable.
Personally, I would go for the lower mileage truck. 200,000 miles is a lot for an 05, and being a company truck and knowing how they are treated I wouldn't want it.

working at a ford dealership for 10+ years people swear by the 7.3 being the one to have, the 6.0's you either had a good one or you got a bad one the tranny's on the 7.3 had some problems but they've offered a HD tranny for a replacement for awhile and if the tranny has ever been replaced its probably had a HD replacement which i havent heard any bad things about them.
The 4R100 is a stout trans, if built right, and if treated correctly. The #1 killer of that trans was lack of cooling, followed closely by a converter that had a lockup speed about 200rpm too low, causing slippage. Bigass coolers and the right converter makes a huge fucking difference on them, its like night and day.
7.3's are the most solid, especially if you go for an 01-03 truck, but the 6.0 is still a strong engine, IF it is the right build. I have dozens of customers with sickohs that are 200-300k on the original engine, most are on original injectors. It all depends on the build version of the engine, there are 3 MAJOR design changes that make a HUGE difference on reliablity.
bombers is a decent site, but like anything on the internet there are quite a few morons in there.

great info... so it sounds like as long as you do your maintenance on it that you shouldnt really have a problem.... i dont really plan on doing a tuner necessarily i was planning on an exhaust / leveling kit thats really about it

ford: best frame; diesel + transmission pairing is good; 7.3=shit on ultra low sulfur fuel, 6.0=ok after 2005, 6.4=not recommended, 6.7=new so high$$
gm: outdated interior; ok frame; duramax is ok; allison transmission is baller
dodge: cummins is baller; transmission is shit; interior is shit
toyota/nissan: get the fuck out of here with that happy meal toy

if you want to know the pros and cons, read up on powerstroke.org and powerstrokenation.com. if you do a search, this topic comes up a lot. before you buy any, get an oasis report be it a 7.3 or a 6.0. i have had experience with both, if you get a good 6.0 you will be pleased.
