Need 5th wheel hitch and information

OMG. This is like a train wreck. 
First, reading comprehension. The lady literally said she has a puck system in her truck (in slightly different wording). 
And lady, if this is the first time you’ve used the internet I understand, but why would you ever just post your phone number publicly, randomly?  Don’t do that. lol. 
You can use the internet to find a retailer to buy one, classified adds to buy a used one. Or a shop to procure and install for you if you’re not capable of finding or installing. (To be fair, puck system attachments are made so that even a person with virtually zero knowledge or ability can actually install it themselves easily. 
Second, assuming you know less than nothing about towing, or you wouldn’t be asking this question. Did you actually jump in with both feet and buy a 5ver and are skilled and knowledgeable enough to do everything required to tow it safely, including towing it safely and not being a rolling roadblock or accident in progress?

sorry for the diatribe, it’s just curious how one can have zero knowledge or understanding of even finding a hitch yet somehow has the knowledge and understanding to tow a big trailer.
