Who has one in their van and what brand?
I have been looking at compustar. They have a diesel ready one with turbo cooldown timer.

I have a python in mine, I have used it a few times, seems to work great.

I have a cheapo avitol 240 installed. also has remote locks. Best investment on the van so far.

compustar very good unit life time warranty on their brain easy install in trucks anyways

I will probable do my own install of the compustar. Every place around me pushes the viper and don't want to install the compustar.
Let me know if there are any tips you can offer, I will be doing an install on my brothers 07 classic as well.

jump ur ignition wires and for the bypass i suggest blade in compustar clean and clutter free 12 volt dot com for wiring help other than that basic stuff good luck

I have an AutoPage alarm RS1000 C-3 oled, it's an awesome unit with a lot of range. I use it mostly on our snow trips. I can start the van from the top of the mountain (at least a mile) and have it warm by the time we get down.
It has all the diesel settings for glow plug warm up and turbo cool down.
The C-3 option lets you control everything from your smart phone with range anywhere you have cell service. Two way communication confirming all commands and activity.

Too Fancy for the work van but would be sweet on the truck
