FYI from 2014 conversation with a dealer in RV show in Quartzsite that retro installs Silverleaf it is a plug and play with the Aladdin if you have that system.
What is normal cost to get a Silverleaf, at $10,000.00 he explained would be right around $5000.00 should your Aladdin fail and you want it to be replaced with a new Silverleaf. You would not have however screen in dash as it would most likely be on a tablet screen unless you also completed dash modifications.
