Doesn't surprise me, Bobby. I lived in the tropics or desert for the 10 years before I moved to Indiana. When I was a kid up in Iowa, Indiana was a southern state. I drove to scholl with the tires of the old Bonneville frozen flat on the bottom peeping though a nickle-sized hole in the windshield provided my my trusty Bic. Now, after 17 years in Indiana with maybe 2 days in total that compare to this last entire month, I have to keep driving to the post office to make sure I haven't been sent back to Iowa without my knowledge.
I reached a day when nothing would start in time. I couldn't get my youngest daughter to school but due to a 2-hour delay, I got the 6.2 started in time to get my oldest son there. Then I dragged the huge torpedo heater out of the loft of the red barn (where we jam) and got the garage warm enough to make me want to work in it. It's a 3-car with 3 separate doors. I do metal work in the left bay so I don't park anything in there. In the middle I have my motorcycles parked at an angle so I can ride the one I want. My wife has the right bay. I put two of the bikes in the work bay and the third across the front of the middle--it's the TU250X that I ride in the winter. My VW fits this way and the garage keeps it warm enough to start.
The E350 van is just dead with its Wal-mart Excide batteries until our March trip to Sanibel. It's on a battery charger. The 6.2 has a permanently mounted charger so 30 minutes with the block heater will get it going. I have to use it a couple times a week.
Both the VW and Powerstroke are direct injection with glow plugs. I don't think glow plugs are very effective on direct injection motors. The 6.2 has the little pre-chamber that is easy to heat. This seems to make a huge difference.
My bus with the hugely long stroked engine and enormous bank of batteries starts easily in this weather. Unfortunately, I have the rear suspension off and the air-ride half installed so I can't use it.
