When Your Trailer Is Attached, You Might Get Some Damage Because Of The Cars And The Ramp, But I Can Fix It! Just Go To The Service Menu On The Right-bottom-corner Screen Then Click Enter, And Press How To Service. Then, You'll Get Towed. And You Can Repair. If You Dont Wanna Spend Money On Repairs, Find Mods That Might Allow You To Not Damage Your Truck. Thank You!

For this problem i wrote the Mod Fix. Read the discription and use it
