Thanks for all the input. I think you have convinced me that the safety factor of having a good 3/4 ton diesel pickup is what I really need to haul a CD.

Here are my towing requirements: I live in Oregon and would tow the CD up I-5 to Anderson Island in Puget sound where I have a vacation home. I would store the CD at that location. Once the CD is on Anderson island, the only towing I would need would be to take it to the marina on the island and launch it and retrieve it.
I'll offer a slightly different opinion. I'm just thinking that it sounds like 99% of your Class B use would be just traveling, for which it would be fantastic; and around 1% of it would be towing to your local ramp. And a Class B would be so nice for that 99%.
I have towed a CD-22 type boat with a 1-ton, dually pickup truck and I'll have to say it came the closest to "hardly know it was back there" of any combo I have towed. That said, the truck is rated to tow something like 15,000#, so it's really no surprise that it handled <5,000# with aplomb. More is always better in a tow vehicle, but for various reasons I wouldn't always opt for it.
It sounds like you don't plan to tow your CD-22 "any distance" on a regular basis, right? Just once to get to your northern home and then occasionally down to the local launch ramp? Not that you want to do that with a VW Bug, but that scenario seems a lot different to me than something like regular cross-country towing. I would be more comfortable using a vehicle that was near/at its limit for those very short tows than for cross-country/regular towing. So maybe there is something to the idea of renting or borrowing a larger truck for the one trip north, and then using a Sprinter (you mention 5-cylinder, but are there newer 6-cylinder models? What about the 3500 dually Sprinter?) - or maybe an older pickup truck for your local to-the-ramp towing. For that I don't see why an older/gas truck would be any problem.
Another possible route: I bought a used 3/4-ton gasoline-engined camper van for towing my 22. It has a 13,000# GCWR and weighed in at around 7400# loaded for my trip (sans boat), so I'm not at the rating but neither do I have many thousands of pounds to spare. On the other hand, I have a heavy vehicle with a nice, long wheelbase and many of the same goodies that the same van with larger engines(s) and higher GCWR's have. I towed my 22 from Florida to Washington state earlier this summer and, while I knew I was towing, and it's not the Ultimate tow vehicle, I found it more than satisfactory, and I really enjoyed/used the Class B camper van capabilities of it. So maybe that's another option.
(Of course if you just *want* a large, diesel pickup and/or you wouldn't feel comfortable with something else, then that's a different thing; I'm just saying that in the grand scheme of towing things, around ~5,000# is not a huge load, and it can be managed with less-than-ultimate tow vehicles.)
Two things I found to be very good:
1) A longer wheelbase (for example my van has a wheelbase of something around 138", IIRC; whereas some of the "just barely 5,000# tow rated vehicles," such as the Highlander or Pilot, had wheelbases more around 109", again going by memory. I think they would be more "squirrelly" on long freeway tows. I would likely use one for a two-block tow though, if they could handle the ramp (maybe 4WD would take care of that?).
2) Good trailer brakes. I have a tandem axle trailer and put new, high-quality disc brakes on all four wheels before leaving on my first trip. I think the van stops better with the trailer than without it now - very nice. (Mine are just surge brakes, btw.)
Again, I won't say my van tows as "unnoticeably" as the 1-ton dually pickup does, but then that could be bested by a Mack truck, I'm sure

Since you are not going to be towing any distance but for the first time, I think you may have other options if you wish to consider them.
Oh, one more thing, which I only touched on above: I haven't done much launching/retrieving with my combo - at the moment the vast majority of my experience is just with highway towing. It's possible that I will find I need/want 4WD for launching/retrieving, in which case I'll change vehicles. But that would be about the traction on the ramp, not towing qualities.

PS: Of course gas doesn't get as good a mileage as diesel. In my case the whole vehicle was so much less expensive (and I didn't want a diesel/noise right "in the van with me" the way van engines sit) that the cost was still quite a bit less. I get 16mpg highway when not towing (up to 18 if I keep it to 60mph or less), and around 12-13 on just "in town" driving. That changes to around 12-13 average when (highway) towing. I'm sure a diesel would do better.
PPS: Note that some folks are speaking of CD-25's, which are more like 8500#+ all-up vs. the 5,000#+ of the 22.
