That is weird, there shouldn't be any chance of that happening.

This only seems to happen if you choose to keep the day cab option when customizing the truck. If you choose any of the sleeper cab options, the truck doesn't get replaced by the Volvo VNR (correction from last post which incorrectly said VNL 2018).

can you post game log please

The warning at the bottom of the log file is unusual. It references the VNR when I believe it should be referencing the Cascadia. I'm not sure how that is happening.

Nah that warning has nothing to do with it. can you post a full log?

What's the best way to post a file here? It's too long to simply copy and paste the whole thing.

post it on pastebin

I think I might have found a fix for this. On my active mods list, I gave the Cascadia higher priority than the other mod trucks. After customizing (keeping the day cab) and clicking the Confirm button, I was returned to the mod dealership and the Cascadia didn't change to another truck. I tried this on my primary profile and created another profile to confirm that this fix works, and it seems to.

After clicking the Mod Dealership, selecting this truck, and choosing customization options, after clicking the Confirm button and returning to the Mod Dealership, the Cascadia is replaced by the Volvo VNL 2018 (mod truck which I also have). It seems with this mod conflict, the only way to customize the Cascadia is to buy the default truck and drive it to a service station to customize it.

well the is the thing guys once you buy a truck like the cascadia the only solution is to custommize at your local repair shop if you wan to keep the truck disappearing from the dealership
