and the million dollar question.. Why?
As for the how, have a Viper SmartStart installed and have them program a custom run time. Then link the SmartStart app to Google Assistant and set up a routine when you want the vehicle to start. Allow notifications to let you know when the vehicle has started.
Thank you for the suggestion and lead, without criticizing the idea. I asked that question on another forum and all of the responses were "less helpful".
I come from the van camping world, but am ( planning ) on switching over to a 2500 or 3500 truck + cap + trailer, for the greater capabilities. I also will use it for misc things for work / tools.
The accessories will be run from a modest ( 10 kW-hrs ) aux battery pack, and the plan is to have solar on the cap to help keep up, but this cannot be counted on all of the time. Generator use is more or less banned or not allowed for camping here in CA, but I can get around some of this by occasionally fast idling the vehicle to make up for it, with sufficient alternator capacity. Charging while driving will also contribute, but driving can be irregular.
I plan to loan the vehicle to my adult children and the grand kids, so it needs to have a more or less bullet proof way of keeping them warm / cool / safe no matter the location, weather conditions or situation.
They might use phone applications, but I don't, unless you call texting a phone application, but it is a good lead and insight. The tracking, other info I really don't want, but maybe that can be turned off.
Mostly I would use the feature in the winter, so maybe it can be end customer adjusted, as I don't know exactly how often I would want to turn it on yet, and it probably will vary, depending on use.
Really appreciate the insight and lead.
