The Museum's BJ74 has a factory shutter. it looks like a roll-up blind. I tried to take a photo of it but it does not show up well.

I had it made by a local shop that does winter fronts for big trucks and skirting for RV's. Just snaps on and off. Cost me $100
The JDM 70's with the winter package got the roll down shutter. I was going to swap it out from my BJ71 before I sold it but the brackets are soldered on to the A/C condenser and I didnt want to drain both systems to do it
Dan, Are you sure it's not just a spider web? You know with your eye sight and all.
In this case I believe I got it.
I'm closing in on my webasto install for my '87BJ74 w/13BT
What do you have your Low Voltage Disconnect (LVD) set at? I know I keep asking but any tips or tricks for operation etc. that you've learned with use? Its freaking almost 50 degrees F here right now!!!! But I have every confidence (and hope!) that Winter will return with lots of snow/cold!!!!

Low voltage from factory is 22 volts I believe. I have never tested it or changed it. I am not sure you can but maybe its possible with the new style oval shaped timer? That said I have also never had the F03 (undervoltage/overvoltage) code come up either.
Thanks! Good to know. I have new (don't know when they introduced it but bought my heater in the fall of 2016) oval control and can set the LVD
Malahki, a couple questions.
What are your thoughts on durability? I know you said you pulled and capped the exhaust on muddy trails but what about full submersion? I offroad quite a bit in Alaska and we end up crossing streams/rivers on a fairly regular basis. I try not to stay in the water long but it's definitely deep enough to fully submerge a Webasto mounted low.
This might be a little more far reaching but how good is the heat output? In addition to pre-heating the engine, I'd like to run a couple coolant lines back to a heater core in a camper on the back of my truck. Might as well use it to heat a truck camper too, right? Probably not going to try this in -40 weather but 0F is a definite possibility.

I have an espar for my -75. it does good. Haven't tried submerging it though, might have to contact webasto and see what they say about water proofness. I have mine mounted on the outside of the frame about where the front seat is, I also installed a splash shield since it is potentially in direct fire from the front tire. as to also using it to heat the cap you might end up taxing the water pumps capability to move the water good enough if you have too much distance to travel? Usually people use a air heater unit if they want to heat a space in a vehicle.
Thanks coldtaco!
I'll contact Webasto (or espar if I go that direction instead) and see what they think. I suppose worst case, I could either mount it higher or fab some sort of aluminum box. Or just stay home!
Good point on the tubing distance taxing the water pump. Perhaps I could mitigate the distance issue by using larger diameter tubing and reducing the backpressure? Or just finding a slightly stronger 12v pump. Worth looking into anyway.
I definitely agree, air heaters are what people typically use. I've actually got an eberspacher in an old VW and it works great. However, I've got a pretty small truck that I use to haul every day and space is at a premium. I'd hate to give any of that up! I really like the idea of a small heater mounted on the frame in space I wouldn't use for anything else anyway that can be used both as preheater instead of an autostart (Webasto Telestart or Thermocall) and as a way to heat my truck cap if I decide to camp in the back. An air heater would take up a couple cubic feet but I could mount a small heater-core with a couple of computer 12v fans in a thin box halfway up the truck bed and loose almost no interior bed space. Or, put a plate on the floor of the truck bed similar to a goose gear system with some tubing routed into the underside and have radiant floor heat. Quite a bit more compact than an air heater.
I have a co worker who is installing a new Espar into his new GM Duramax. What I did learn is the Espar now uses
a separate water pump from the heater unit. Kind of interesting, but worth seeing whether they have the ability to
pump through a larger system like heating the rear. I know that my older style Webasto TSL-17 was capable of
producing enough flow for a large sailboat. Anyhow, just my .02 worth. I'm looking at a another truck now, and
a coolant heater is sort of on the list for later on.
