Me, I have an inexpensive Express Van, so just a stick to choose the idle speed - about 1000 rpm per Mr. booster. Well, until booster publishes an update.

New I guess for 2018. I have a fixed high idle package that can be started automatically through Silverleaf controls at any programmed SOC of the battery, manually by the MB key fob or security Drone fob or remotely through my iPhone Drone app. Their are more sophisticated controls on Silverleaf where you can lock out Auto Startup say from 10 PM to 7 Am to honor quiet hours in a campground or even exercise it on a pre-programmed basis.

In that video it appears that adjustable is really just a user controlled button on the dash for either on or off. I was assuming adjustable meant setting the idle as in 1000, 1100, 1200 rpms, etc.

So it turns out this Sprinter does have the adjustable idle speed. It's called ADR (working speed governor) and there are three buttons on the left. One switches the system on (if you're stationary and the parking brake is on) and then idle up and idle down. Normal idle on mine is 650. Pressing the increase button I got it up to 1800 and decided that was enough. It does make a nice difference with the GU charging the lithium.

It looked to me like you could ramp it up and down.

It's a real plus, particularly with a 1600ah battery bank. What does your documentation show for model year and chassis year?

Yes, WingedRyno confirmed it.

Boondocked at Wally World last night, chillin' at a park right now. Had to run all kinds of errands related to moving out of our condo and getting it ready to rent out.

I'm still working on the A/C test but I strongly suspect it's not up to specs, I just haven't found the specs yet. But I cannot imagine it's within them.

I'm still trying to figure out the subtle art of black tank dumping. I can't seem to empty the tank all the way. Although waiting until it's at least 2/3 full does seem to help but I'm not sure if I'm stopping before it's done and not judging the sound correctly or what. Got it down to 1/3 empty at any rate.

Finally got the reflectix up but it's still hot in the van. While at Wally World the van got up to 102F (it was in the high 80s low 90s outside) and I used up two EcoTreks with the A/C on part of the time to try to keep cool.

We have a week of cool weather starting tomorrow so I'm really looking forward to that. I love the lithium!

Really enjoying this thing and can't wait to get it set up just right and the A/C fixed and then pick up the wife when her reserve duty is done so we can full time and go enjoy nature. What a great way to live!

It is really helpful to have a clear segment somewhere in the dump chain. There are various fittings that make this possible. What is appropriate is specific to your particular setup.

Tank gauges are notoriously inaccurate. If you have a macerator you can tell from experience by sound if you emptied the tanks, or just check the outlet for discharge. It it sputters it is nearly empty. I don't worry about emptying it out all the way since I still want liquid in the bottom of the tank.
