Wow . . . color me lame for having let this thread sit for two months.
The only defense is that I've been out a lot in this truck, and have also been doing some minor changes, though I haven't yet lost the ability to use the truck for hauling. It worked well to take the Icon Designs Ural motorcycle Scott Brady borrowed in Portland through some bad weather down to Roseburg, and I hauled home a bunch of plywood sheets which later got cut up for some of the interior furniture, which is kind of cool when you think about it. I've got pictures of the changes that I'll get posted up in the next few days. But I also made one really good change worth mentioning now, though there's not anything to look at.
The most recent trip was nine days and about 1600 miles down to the Redwoods and in and out of the Cascade river valleys. Really scenic stuff. And in spite of mediocre and worse weather, all went very well.
Part of that was because I swapped out the standard cargo van springs and replaced them with the springs used for the passenger version. Without very much heavy stuff in the rear, the cargo springs didn't have enough weight on them, so the van bounced and crashed over all the bumps. So switching to the passenger springs was a really good idea. The ride was way better with lots less pounding, as expected, but the more compliant springs also helped with the handling. We had no problems with some very curvy and often broken pavement, and I think I would have before the switch, or even on my previous conversion. The LTX Michelins I put on when I bought it probably didn't hurt, either. Anyway, the Sprinter rides VERY nicely now. Driving hundreds of miles at a time is no hardship.
I suppose I also ought to brag about the fuel economy. Three fill ups, one at 22+, one at 23+ and the last one at better than 24 mpg. And that was with a lot of up and down and some start and stop thrown into every leg. It's making it tough to give up this little 5-banger for a new model.
