Why is FR3 called a "Crossover"?

[max49]

They say it's got drivability like a CL C with roominess of a CL A

They don't say this about the Georgetown, so what is different about the FR3 and say for instance the GT3?

A salesman told me it was a CL A built on a CL C chassis, but I don't think could be right since they seem to have the same chassis specs.

I have not had any luck googling this question.

Thx in advance

Fleetwood and Forest River used the same term to define some of their smaller, lower priced RV's back in 15-16. They used the term to describe a Class A that competes with a Class C in terms of size and price. I assume it was used for marketing purposes. Here's a link to Motorhome magazine where the term is used by both companies:
