In resale that was the killer. Shipping to customers outside the US was such a pain we eventually just stopped. Felt bad, but many European customers were very demanding and unforgiving to a highly complex system that's mostly out of our control. Which is a huge bummer to those who needed to get parts from the US and we were the only ones that could get it.
In the shop we had many customers just buy new trucks and scrap the 5 year old ones because it cost them more money sitting in the shop than on the road.
