No fist off if the gooseneck hitch you purchase later is a bolt in kit then it won’t work in any other place but over the wheels. The frame jumps up in that location to be closer to the bed. If you have a custom made set up that won’t matter.
Second steering and braking will suffer greatly. Ask your self… if you wreck even if it’s not your fault will your insurance, the state troopers investigator, the other persons insurance and the courts be ok with it? Even if a wreck isnt your fault at all some one could easily say you could have avoided the issue IF your goose neck was in the right place and they can assign a certain percentage of fault to you. It’s the same thing with guys towing over legal weight.
