Hi Paul and Amanda,
Retro fit would mean you having something done after your purchase.
Option would be something you can order from Heartland when you order your RV.
At this time, for Big Country, we do not offer an Auto-Leveling system.
For an after market retro-fit system, there are several out there. Most of them work well, but not all of them are approved by your RV's frame maker, Lippert.
I've moved your thread out of the ATF, here to: Forum - HEARTLAND RVs GENERAL AREA - External Components - For all Heartland brands - Landing / Leveling / Stabilizing Gear
Others can weigh in and tell you what they have used or what they have researched.
Jim
