Best option to extend the hitch under my camper?

It depends on customer vehicle. Some vehicles have the option bolting on an extra hitch on top of current hitch. Other vehicles are complete replacement only.

I just watch the video on their site & see i will need to trash my factory hitch anyways for the dual system they run, & I'm very interested & just emailed a link a guy that does work on my toys for me to get an estimate being it seems you buy the kit & must get it it installed yourself?
