new to the forum but why not jump in with a question. i did a search but couldnt come up the answer. my friend is getting a new mule 610 4x4 and he is having them put on a trailer hitch. he was concerned about being told that it only had a 80 lb tongue weight limit. does this number sound correct or is it a safe number. is it a matter of the material the hitch is made of or the strength of the frame.
