I am pretty sure the new Honda diesel is an aluminum block. Not sure about VW & MB diesels.

Aluminum is never a great idea for a diesel because it dissipates heat faster than iron. A diesel runs on compression-generated heat, so if that heat is leaving the cylinders quicker, it must be constantly regenerated - meaning the engine will have to work even harder just to burn its fuel.
For full-size pickup trucks, the weight of an iron diesel is not that big a deal. The Cummins and Powerstroke are all-iron, the Duramax (and Jeep Liberty diesel) is iron block and alum heads.

"kc" has a good point there. Heat is an absolute necessity in a diesel engine. When the cylinder temps drop below a certain point, all combustion will stop. I can point you to at least one guy who had his engine shut down due to low cylinder temps. He was descending a long grade, foot completely off the accelerator. He just happened to glance at his exhaust temp gauge and noticed it was below 200*. He had never seen it that low and really didn't think much of it, but kept watching it anyway just to see how low it would go. It kept going down to around 160* where the engine shut down just like he had turned off the key. The truck had an auto tranny, so when it died, the torque convertor unlocked and he lost all power steering and brakes. We all know you can still turn and stop, but he said it was all he could do to stop the rig. He said he was literally standing on the brake pedal with both feet just to slow down. If it hadn't been for the electric trailer brakes doing most of the stopping, he had to work those manually, he doesn't know what would have happened.

It will be interesting to see how these hold up being all aluminum. They tested them pretty hard in the high speed trials. That is different than starting and stopping on a cold winter's day..
The all-aluminium i-CTDi employs second-generation common-rail technology to provide further advances in fuel efficiency and refinement. It also features a turbocharger and four valves per cylinder. It will fully comply with Euro 4 emissions standards. In short, it will deliver smooth, refined, high performance motoring, matched with frugality and particularly low emissions, perfectly complementing the character of the new Accord range.

I have an opportunity to buy an automatic 2005 Chevy 3500 gasoline model. Brand new. for $23,000. I want a diesel, but am having a hard time passing up this truck. My plans are to put a flatbed on this truck, and will probably pull a 24 foot dual tandem gooseneck.
My quedtion: Will I be happy with this truck for the price, or will I regret not getting a diesel truck?

If I was towing a trailer that size on a regular basis, I would go diesel for sure. If you only tow it once in a while the gas will do fine. It is so much easier to tow with a diesel engine torque. They do cost a lot more and rarely do you get the rebates offered on the gas trucks. My brother-in-law just made that choice. He saved the $7000 premium and got the Dodge Hemi. He only tows once a year to Bonneville and could live with the gas engine for that trip.

The following Al block diesel engines were available in Europe as of 2004. I don't think heat retention is a problem for passenger diesel. They run much hotter than truck diesels.
PSA-Ford Duratorq 1.4 and 1.6
DaimlerChrysler 1.7 liter (Mercedes A klasse)

A reporter would like to interview diesel passenger car and pick-up owners and Southern California residents who'd like to buy a diesel passenger car but can't because new ones aren't sold in California. Please respond to jfallonedmunds.com by Thursday, July 14, 2005 with your daytime contact info, vehicle year/make/model and city/state of residence, and put the word “diesel” in the subject line.
