D-Series camper shell add-on

so the camper shell on D-Series is broken and yes i did use safe mode and it wasn't broken and i did try disabling all the mods to see if their was conflict and there wasn't any conflicts. I am using the current version of Beam ng drive. it doesn't do it in official configurations. when I customize a official config in-game it breaks but like the beast config it doesn't break

 

I have the same issue but it only breaks when i use the long bed. It seems to be fine with the regular bed. I did a clean install last night due to a white engine problem with the d-series, that is fixed now i have this problem. its like what the actual fuck is going on.
still love this game to bits!
but this problem needs to be fixed

 

I also have this issue. Sometimes it´s fine though. Anyone found out the cause of the problem?

 

I have the exact same problem too. It's only ever with the long bed, but it's still annoying.

 

it is most likely the rear corners above the taillights clipping into the glass of the topper causing clipping and making the topper useless to use.
I could be wrong but going into 2 even 100x slow motion when pressing "R" then you can see that the camper glass clips and causes damage.
My guess, i could be wrong but in my opinion it makes the most sense instead of just thinking something is wrong with the camper itself.
