Hi guys, today I was out on the woods pulling a trailer with a couple side by sides. my trailer got stuck, when I gassed my truck which was on 4 wheel high it felt like it squaded the rpms when up but I was expecting the tires to spin out or something but it did not do a thing. it is an 08 silverado with a lift is this normal? my older 4x4 will break lose when pulling something that is stuck.
