I cannot pull it out of the receiver. I think it's rusted in pretty bad. I've tried spraying multiple rust products in there... I've also spent hours banging on it with a hammer/sledge. I've tried angling a jack on it and prying it out. I've tried chaining to another truck and pulling it out (the road was snow covered and we ended up pulling eachother back and forth!) The things which I have in questions are...... 1) Torching it.... will this work? What type of torch? 2) Chaining to a large tree, driving like 20mph and putting the truck in Neutral before the chain is pulled....... what do you think?
