Geo,

I saw your question re: a partial belly pan. I think any amount of belly pan is going to help. There's so much acreage under those things and it's generally just greeblies and bits out in the wind. You can cover up most of it, I think, with impunity. Be careful around the driveshaft and exhaust lines, obviously.

I haven't done any pan work on my truck, but when I do I intend to start at the rear and work my way forward. A natural stopping place will be directly abaft the rear axle, then pick things up again ahead of it, etc. If I can do any kind of fairing work to smooth the airflow around the axle, I'll do that. But I bet if you take a peek at your underside, it probably looks approximately as smooth as the Grand Canyon.

+1 to what Frank said about mirrors - I drive an Isuzu NPR at work sometimes and that thing is only half the length of your rig. If I didn't have mirrors on it, I just wouldn't drive it. But there are lots of kits out there for adding backup mirrors to just about anything, can you bolster your existing mirrors with a few of those? Maybe you could improve the rearward view to minimize your mirror area and still have a good picture around you.
