Very much so baby bankroll, that's great advice. While you are watching reliability and teething problem you could be saving also for the Renegade for a huge down payment to have cheaper monthly to help with child expenses.Pretty much this.
You have at least 9 months minimum to wait and see how the Renegade turns out even if happy news visits you tomorrow.
The only exception would be if getting a Renegade now would lower your monthly payments.
Kids are expensive, so building a baby bankroll now would be wise.
