I'm trying to order a 2500 AT4, but the dealer just said there's an issue and they'll let me know next week if they can order. I'm not holding my breath though. According to Donlen's the wait is 26 weeks and no new orders after 1/1 I assume because they'll be switching over to 22's by then. Unfortunately there's no AT4's in my area and dealer says swaps aren't happening either. Sounds like I'm outta luck till August.
