Is there such a thing has a toyhauler on a truck camper...

Wasn't sure under which subtopic to post this so am doing this in two areas.

Tried googling the subject and then went to youtube to search, which was a REAL mistake as started watching videos for two hours but why has this not been invented, logical, rational speculations are allowed and perhaps this will give a maker an idea to create one. Don't like hauling vehicles so that's why I want something like this.

Want to bring an Elf by Organic Transit.
