My original pre-order from November 2018 was for a max pack. i switched to the large pack to get my truck sooner. i got it in March and i love it and i am happy with the large pack, even 7k miles later. If you will do heavy towing over distance then you need the max pax, period. But for everyday driving, and the occasional boat trip to the local lake, the large pack is great. Hope this helps!
