im starting this thread for guys like myself who want to keep what they got and just add some options.i would prefer to discuss factory options but aftermarket is ok as well.my van is an 08 2500 baseline,that i added some options to.some were easy some were complex.so far i have.............1)map light
2)compass and outside temp
3)trailer wiring
4)trans cooler
5)audio controls (steering wheel)
6)cruise control
7)headliner cubby
8)key chime
future upgrades planned are power windows and door locks,illuminated sunvisors,backup alarm................................in 2012 they added parking aid to the vans but i believe it would need a bcm reprogram so probably have to go aftermarket if i wanted to go that route.....undecided at the moment.if you post please note what type and year your van is

 

Sounds like you have been busy…keep posting your progress..
