Auto leveling is great feature. But I'm not sure I could justify the cost of an aftermarket install. $4000-$5000 grand is a big number?
I would really have to look at my trade in value and overall cost to upgrade were.
I would have to consider putting that 5K into a newer RV vs. putting it into a leveling system. Although I understand it's hard to start over when you have a rig that you are comfortable with that has all the kinks worked out.
I also think I would be more inclined to start over with an aftermarket system vs. retrofitting what I have.
I think I would want parts designed to be synced together vs. manipulating my existing system.
