Between the weight of people, gear, cargo, full tank of gas, the hitch itself and pin weight, will you be within the rear axle and tire ratings? For the size 5th wheel one could tow with an F150, I would much rather opt for a comparable travel trailer. If all is etched in stone, I'd go with the hitch the dealer wants to install. Having let a dealer install my first 5th wheel hitch out of convenience, I will never again pay to have one installed. I installed the same hitch in five more trucks and did a much better job.
