Hey folks, I'm glad I stumbled on to this site. It seems to be right up my alley. First, let me give some background on myself.
I'm 34, married, and have my first child (son) due in about a week. I live in Northeast PA, have a bachelor's degree, and am a project manager for an engineering firm.
My current vehicles are:
2005 Dodge Ram 2500 QC SB 4x4 w/5.9 Cummins (auto)
2008 Toyota Camry V6
I know, they aren't your typical eco-type vehicles, but let me continue...

I did have 2006.5 VW Jetta TDI. We loved the car, consistently got 42-45 mpg and put 115,000 miles on it in less than 4 years (we commute a lot). The turbo (actually, the wastegate) went on it (out of warranty) and the DSG tranny started to show signs of problems. With a pregnant wife and winter coming, we wanted a more reliable car. So enter, the Camry.

Anyhow, my truck is my focus for this site. The 3/4 ton rig, as you may know, doesn't have any EPA estimates on MPGs. From being a member on several forums and having a few friends with various models of Dodges with the 5.9 Cummins, I have seen City mpg range from 13-16 and hwy 16-20. A lot has to do with gearing (I have a 3.73 in mine), but the 4.10 is a fuel pig. When I first got my truck, I was seeing ~15-17 city and 18-20 hwy.

I'd done a few mods and am now seeing 18-20 city and 24-26 hwy. My goal is 30 mpgs on the highway, but we'll see. I still have a few mods to make. It's worth mentioning, that my numbers above come from hand calculation. As my OBC is very optimistic. On highway, when I'm doing the speed limit, it quite often reads 30-33 mpg (I wish).

My wife and I make several trips to GA every year. It's about a 850 mile trip. We've made it half way thru SC before fill up (750 miles or so). My next milestone is GA border (which is ~780 miles), then the 800 mile marker is the following milestone. Ultimately, getting to our destination without a fill-up would be awesome.

Here's my current list, in chronological order, if I recall.
5" Turbo back exhaust with free-flow (too loud though) muffler (RPM Outlet)
Solid fold tonneau cover (Extang)
Fuel Mgmt tuner (Quadzilla)
Larger intake manifold elbow (Banks)
K&N (larger than stock) filter
Michelin Low Rolling Resistance Tires (slightly taller/skinnier size than stock)
Bully Dog Triple Dog Gauge/tuner (normally set to stock tune)
I often run / rotate fuel additives (Power Service white or grey and Lucas diesel treatment.

I just got my flex-a-lite electric fan this week and hope to install it soon.
Future mods include:
Cab-high cap
Air dam to fit under bumper (this is a stock item that the previous owner removed)
More free flowing exhaust manifold (BD or aFe)
Manual Locking front hubs (Dynatrac or other)
Upgraded (more efficient) torque converter (Few option)
Larger, more free flowing intercooler (Banks)
2nd overdrive gear (article in diesel power mag)
At some point, a water/methanol injection kit (Snow Performance)

My goal has always to do efficiency upgrades without losing any feature or amenity (deleting the power steering, AC, or wipers are not options), to keep the look close to stock, and to keep it useful for what my intent for it is (hauling dirt, mulch, wood, towing, commuting long distances).

I'm open for other areas/ideas of improvement....with my list, I think the main issue is aerodynamics....which will be tough to keep a relatively stock look intact.

Anyhow, I thought I'd introduce myself. Oh yeah, I made my own biodiesel for 2.5 years.
