I also have a jump start with a compressor. I make sure its charged before we leave on a trip and plug it into the accessory plug in the back of the Escalade while we travel.
I use it primarily to power the electric jack that I use to fine tune the
Casita leveling after we set up camp.
It is also useful to add pressure to the
tires on both RV and TV before leaving a campsite. Don't want to lose a tire tread due to low pressure in the
tires.
