Other than making insulation/D2 installation a bigger priority, I'm going to order a tambour router bit and do some experimenting.

Biggest plan change: I want a way to "isolate (hide) the sleeping quarters" .. i.e. make the bed disappear while leaving it setup.

Other biggest plan change is I think I'm going to put another maxfann over the bed.
We *really* liked the maxxfan and how well it worked.
Camping in keywest pointed out how nice it would be to put air straight on us while relaxing in bed (in one fan and out the other).

Fuel mileage sucked.

I even tried adding Diesel Kleen a few times to improve it.

The best I saw was 21.4 over a 400 mile tank in southern Florida when we slowed down and spent some time exploring the everglades and key west.

Today, crossing Nebraska & Eastern Colorado with a 30+mph headwind and the cruise control on at 75mph.. I averaged ~15mpg

Due to the large number of miles traveled in a short time I had to keep the average speedup. We were normally going 70+. That and we couldn't get a break on headwinds lead to an overall average I'm guessing in the 17-18mpg range.

Somehow we had a headwind going east
...and then the expected headwind coming back west.

I suspect the fuel bill is somewhere around $1400 for the trip.

Most expensive diesel: Key Largo, Florida = $4.00/gal
Cheapest: Gary, Indiana = $3.59/gal

not a good thing.

I'm guessing a D-2 will be moving enough air on high to be equal to a complete air change every 2-3 minutes? that's a huge rate of air turnover.

if you were really trying to buck the winter weather doGs, then snag a basic furnace air filter from Home Depot and make a cardboard & duct tape box / holder / adapter so the Espar stays happy.
Awesome advice! Thanks!

I also realized today: don't put the Espar's exhaust pipe under where the fueling occurs (as one pump overflowed and made a mess )

Sleeping in van 10 nights in a row = savings of $1000 in hotel bills.

I only have to sleep in it every night for the next 20 years to make the van pay for itself.

Thanks for the advice on the glow plug swapping space.

I haven't quite determined location yet....
Because I've luxury lined the bottom boxes, I think under the bed in a side box would be good for "not hearing it" while in bed..

That said, A guy on Sprinter forum put his under the passenger seat and it was a really cool/neat installation (and it would be blowing air rearward toward the sleeping quarter).

That said.. I was considering putting the coach batteries under the seat..

i.e. tbd.

I don't remember if you changed your tires to a bigger size or not, but if you did, and are calculating your fuel efficiency by measuring distance travelled (on your odometer) by fuel consumed (at your fill up) you might be making an erroneous calculation. The bigger tires roll a longer distance with each revolution, and consequently, you think you are travelling a shorter distance than you may have travelled because of the fewer revolutions per mile.

I noticed a "drop" in my fuel efficiency on my car going from a 225/50R16 to a 205/65R15. Although, in my case, the speedometer is dead accurate now.

That was also my reason for calculating mileage on the first day I got my van. On the second day I switched my stock 235-75 with 265-75. Won't be able to get another accurate mileage figure until I recalibrate the speedo.

Geek; I was going to ask you the same thing- are you calculating from your odometer, and is it accurate?

With the bigger tires on my van, my odo is off quite a bit. But when I calculate mileage using the the gps odometer, I'm actually getting better mileage with the oversized tires.

That's a good point gents.. the bigger tires have my speedo reading 1-2 mph under actual now (it used to read over actual).
I have no idea how much the odometer is off.

The odometer in the van says we did almost exactly 5000 miles on the trip (within 10 miles?). I'll trace out the exact route on google maps (down to the turn) and see how many miles we actually did. I don't think it'll be that big of a difference though

My odo vs gps with bigger tires makes the odo about 5% low. So when I calculate I add 5% to the figure.

Geode: how do the Espars do at altitude? I'm assuming I'll need it programmed for high altitude since the majority of our adventure camping will be over 8500 feet?

Know anything about the Webastos? Apparently they have "high altitude" programming available

From the webasto website faq:

4. Do Webasto heaters work in high altitudes?
All Webasto heaters operate reliable until an altitude of 2000m. For altitudes above 2000m it is possible to adjust our heaters. Please contact your local Webasto dealer for further details.
Some of our products already come with an integrated switch for high altitude operation when needed, e.g. our diesel cooker and the new Airtop EVO series.
