NO - we don't have an end date from RAM.
The discount is DEALER discount not a rebate, so it is up to our owner based on business volume, changes in any internal strategy, or changes to our cost or benefit structure from RAM (whether that relates specifically to the RHO or across the board)
The more looming concern would be a price increase from RAM, based on experience with TRX, Wrangler 392, etc - they could do that intermittently throughout the model year.
Keep in mind it'll be a pretty wide range of delivery window once they start production anyway, so trying to nail down a specific date to receive it by ordering on a specific date... doesn't always pan out that way regardless.
