I've done a few trips in the US through Utah, Nevada... etc, but I was lucky enough not to have any problems. I did prepare for them.... Here's what I did:
Print off the Delica L400 Users manual -
http://www.delica.ca/forum/viewtopic.php?f=71&t=7500 I have it in my glove box and is an excellent reference for general questions.
1)- Have a good toolbox - A good method is every time you do work on your Delica, make sure a matching tool is in your toolbox. We could probably start a whole thread on what's in your toolbox....
2)-Cary a good air compressor, and tire plug kit. Also make sure your spare tire is good and an acceptable back-up for the terrain you are in. Practice changing it BEFORE your trip...haha
3)- I bring a "short" oil filter in case something bad happens and I puncture one. I wouldn't run the short filter for the full life of the oil, but it's compact (easy to pack) and could get you out of a jam until you can order parts. -

4)- pack some spare oil
5) I always carry a tube of JB Weld, and High Temp Silicone Sealant, some pieces of rubber and hose clamps to patch a leak. Again not a permanent fix, just gets you out of trouble, or to the next town.
6) I carry a small netbook for emails, but it also has all of the electronic copies of the manuals on it (Electrical / Mechanical). If you don't have a laptop, buy a cheap memory stick so you can take the manuals with you.
7) If I'm going off-road, I have a great GPS loaded with the route, and I also carry a SPOT GPS beacon in case I really get into trouble and need help.

That's all I can think of for now.... I'm sure I've missed something.... Oh yes, Don't forget to have fun!!
